The Organized Kitchen

Last week our ward had an Enrichment where we prepared our own freezer meals and went to a class taught by a Professional Organizer in our ward, Sandy Jones. I tried to take a few notes and thought I'd put them on our recipe blog. I'm not sure how often I'll refer back to them, but I wanted to keep them handy JUST IN CASE. She mentioned a lot of cool storage products she uses, so I'm sure I'll want to remember the names of them. Below are just a few notes.

The User Friendly Fridge
Rid the Rank:
- Check expiration dates.
- If you have six bottles of different types of mustard, narrow it down to one or two bottles that are used most often.
Plan the Space:
- Educate yourself on what foods belong in the fridge. For example, potatoes, onions, garlic, and squash last longer outside of the fridge.
- Plan food quadrants: keep ready-to-eat/grab foods in one quadrant.
- Never put eggs, milk, or any food that easily spoils in the door - that is the warmest place in the fridge.
Misc Tips:
- Store foods in clear containers (So you can see what's inside. Nobody will bother checking what's inside a mystery container).
- Containers should be square or rectangle to take better advantage of space. Circle containers waste space.
- Use labels on containers and date them. Leftovers should generally be used or thrown-out after 3 days.
- Invest if quality, clear airtight container. (Tupperware favorite: "Modular Mates"-stackable, consistent, "FridgeSmart" - keeps lettuce and berries fresher for up to 2 weeks).

The Practical Pantry
A Clean Slate:
- Clean out messes.
- Check expiration dates. Put items that will expire sooner near the front so they'll be used before others.
- Limit pantry space to foods and paper products.
- If you're going to put things in your pantry floor, put them on a rollable cart so you can pull it out and sweep under it.
My Own Grocery Store:
- Use tiered shelves so you can show cans in the back (but buy Expandable Jumbo Size).
- Put like-items together, like at the store. (Soups, Fruit, Tomato Sauce, etc./Pastas/Breakfast Items/Snack Items/Baking Items, etc)
Creating Extra Space:
- The "Elfa" Door System can hang on door without causing any damage to it. Creates a lot more space in your pantry.
Getting Fresh:
- Keep a list/inventory of odd/unusual products in your pantry (i.e. olives, green chiles, pumpkin).
Misc Tips:
- Label containers.
- Store products in STACKABLE items. You can't stack cute baskets, therefore you aren't taking full advantage of your space.
- "Akrobins" by Tupperware.

Nutrition 103: Guidelines for Weight Loss


When diets don't work and weight is regained I want to remember that a healthy weight is achieved by gradual and permanent changes in lifestyle habits. Here are a few guidelines that I want to note:
  • Decrease the amount of total fat eaten. Fat has more than twice the calories of carbs and protein. Even small amounts of high fat items contain large amounts of calories.
  • Eat a variety of foods and do not restrict certain foods from your diet. Limit dessert foods to one or two times a week instead of after each meal. Forbidding foods often makes them more desirable, and may undermine weight loss efforts.
  • Eat a good breakfast. 
  • Try not to eat before going to bed. Food eaten at night is not burned up and is more likely to be stored as fat.
  • Slow down - don't eat so fast! Eat single portions of food to give the body time to signal that it is full. Give the body time to think! 
  • Eat foods high in complex carbohydrates like breads, cereals, pasta, rice and other grains, fruits, and vegetables. 
  • Exercise. Walk, job, bike, and rowing are great examples of aerobic activities. 
  • Do not starve yourself! Low calorie diets may slow a body's metabolism, making it harder to lose weight. 
  • Lose weight slowly, 1 to 2 lbs a week is desirable. The body cannot burn off more than a few pounds of fat per week. Faster weight loss is probably due to muscle breakdown.
  • Set reasonable weight goals.

Tips from my friend, Heidi:
- Eat six lighter meals per day; this helps raise metabolism
- Avoid complex carbohydrates at dinner
- Reduce sugars
- Do not skip meals; this decreases metabolism 
- Increase proteins, decrease carbohydrates. Snack on lunch meats, nuts, oatmeal with fruit, protein shakes, etc.
- Calculate protein in bars and shakes. Subtract "Dietary Fiber" from "Total Carbohydrates". Total Carbs should be within 10-12 g of Protein. 

Nutrition 102: "Heart Healthy" Substitutions


1 lb Ground Beef: Use 1 lb Ground Turkey- reduces total fat, saturated fat, and cholesterol
1 oz. Cheddar, Swiss, or American Cheese: Use 1 oz lowfat cheese OR use 1 oz part-skim cheese (Mozzarella)- both reduce total fat, saturated fat, and cholesterol. 
1 Egg: Use 2 egg whites  OR use 1/4 cup low cholesterol egg substitute- both reduce total fat, saturated fat, and cholesterol.
1 cup Whole Milk: Use 1 cup skim milk - reduces total fat, saturated fat, and cholesterol. 
1 cup Cream: 1 cup evaporated skim milk - reduces total fat, saturated fat, and cholesterol.
1 cup Sour Cream: Use 1 cup nonfat sour cream OR use 1 cup plain nonfat yogurt OR use 1 cup lowfat cottage cheese plus 1 to 2 tsp lemon juice, blended smooth - all reduce total fat, saturated fat, and cholesterol. 
1 ounce Cream Cheese: Use 1 ounce nonfat cream cheese OR use 1 ounce Neufchatel cheese -both reduce total fat, saturated fat, and cholesterol. 
1 cup Butter: Use 1 cup margarine or 1 cup vegetable oil - both reduce saturated fat and cholesterol. 
1 cup Shortening: Use 7 fluid ounces of vegetable oil- reduces saturated fat.
1 ounce Baking Chocolate: Use 3 Tbsp cocoa powder plus  Tbsp vegetable oil - reduces saturated fat.

Nutrition 101: Lowering Fat Content in Diet


MEATS, FISH, POULTRY 
- Choose lean cuts of meat with fat trimmed such as beef-round, sirloin, rump steak, loin; Poultry without skin; Pork tenderloin. 
- Decrease "Prime" grade meats, Fatty cuts like: corned beef, brisket, short ribs, spareribs; goose, duck, organ meats, sausage, bacon, hot dogs, regular luncheon meats.

- Decrease whole milk, cream, half & half, nondairy creamers, real or nondairy whipped cream, cream cheese, sour cream, ice cream, custard-style yogurt; high-fat cheese like Brie, Swiss, American, Cheddar.

EGGS
- Choose Egg whites, cholesterol and fat-free egg substitutes
- Decrease Egg yolks (substitute 2 egg whites for 1 egg)

FATS, OILS
- Choose unsaturated vegetable oils (in limited quantities): corn, olive, peanut, canola, safflower, sesame, soybean; fat-free mayonnaise, cream cheese, and salad dressings; mustard and flavored vinegars (when cooking, use spray oils or nonstick pans and decrease amount of fat in recipe by 1/3 or substitute applesauce for fat).
- Decrease butter, coconut oil, palm kernel oil, palm oil, lard, bacon fat. 

BREADS, CEREALS, PASTAS
- Choose breads like whole wheat, pumpernickel, rye, pita, bagels, English muffins, rice cakes; lowfat crackers and bread sticks; plain cereals (hot and cold); spaghetti and macaroni; any grain; dried peas and beans. 
- Decrease croissants, butter rolls, sweet rolls, pastries, donuts, most snack crackers, granola-type cereals made with saturated fats, egg noodles, pasta and rice prepared with cream, butter, or cheese sauces.

VEGETABLES, FRUITS
- Choose fresh, frozen, and canned (no salt added).
- Decrease vegetables prepared in butter, cream, or sauce; fruits served in glazes. 

Cooking 104: Herbs & Spices

FRESH SEASONINGS
  • In recipes, cut salt in half and add more fresh herbs and spices.
  • When doubling a recipe, herbs and spices should only be increased by one and a half times. Taste, and then add some if necessary.
  • Add sage, bay leaf and garlic at the beginning of the cooking process as they have a strong flavor. herbs with more subtle aroma such as basil, parsley, fennel are best when added at the end of the cooking process to preserve their flavor. 
  • Delicate aromas can be lost due to overcooking.
  • Cut or chop fresh herbs to expose more surface area. This will release more flavor.
DRIED VS. FRESH HERBS
  • 1 tsp dried herbs = 1 Tbsp fresh herbs
  • 1/8 tsp garlic powder = 1 medium clove of garlic
  • 1 tsp onion powder = 1 medium onion, finely chopped
  • 1 tsp ground ginger = 1 tsp grated fresh ginger

Cooking 101: Basic Terms


Al Dente
-- Describes foods, especially pasta, cooked only until soft enough to eat, but not over-done. The Italian translation is "to the teeth."
Blanch -- Blanching is a process in which food is briefly plunged in boiling water for a moment, then immediately transferred to ice water to stop the cooking process. Blanching tomatoes or peached for about 20 seconds makes them easier to peel.
Braise -- Braising involves cooking a food in a little fat to brown, usually on the stove top then covering and cooking slowly until done. This is particularly suited to less tender cuts of meat.
Broil -- To cook food directly under or over heat source, usually in the oven under the top broiling element or on the grill.
Butterfly -- To cut a food down the center, but not quite through, leaving both halves attached. The food is then spread to resemble a butterfly.
Cure -- To preserve food, usually meat or fish, by pickling, smoking, drying, salting, or storing in a brine.
Cut in- To incorporate solid fat into dry ingredients using a pastry blender or knives. 
Dash -- Less than 1/8 teaspoon.
Deep-Fat Fry -- To cook in hot fat which is deep enough to completely cover the food.
Deglaze -- To add liquid to the pan in which meat or other food was cooked. The liquid, usually broth or wine, is heated to loosen the browned bits left in the pan, and is often used as a base for sauce or gravy.
Dredge -- To coat food with a dry mixture (usually seasoned flour or crumbs), either by sprinkling, rolling, or shaking the food in a bag with the flour or other ingredients. 
Egg Wash -- Egg yolk or white mixed with a small amount of water or liquid then brushed over baked goods to give color and sheen. 
En Croute -- Food baked in a crust.
Evaporated Milk -- A canned, unsweetened milk from which 60% of the water has been removed. 
Extract -- Concentrated flavors from various foods, usually derived from distillation or evaporation.
Fold -- To incorporate a light mixture with a heavy mixture, such as beaten egg whites into batter or custard. The lighter mixture is placed on the heavier mixture, and a spatula is used to gently cut down and through the lighter mixture of the bottom of the bowl then up again. Repeats until mixtures are combined. 
Fricassee -- To cook or stew pieces of sauteed meat in a sauce, usually with vegetables. 
Gratin Dish -- A shallow baking dish or pan, usually round or oval in shape.
Infuse -- To immerse tea, herbs, or other flavoring ingredients in a hot liquid in order to extract flavor.
Jigger -- A liquid measure equal to 1-1/2 fluid ounces.
Julienne -- To cut food into thin, matchstick strips. Julienne strips are usually about 1/8 inch thick, but the length varies.
Mousse -- A sweet or savory dish, made with egg whites or whipped cream to give the light airy texture. 
Mull- To flavor a beverage, such as cider or wine, by heating it with spices or other flavorings.
Parboil -- To boil a food briefly, until partially done. A good might be parboiled before adding it to faster-cooking ingredients to insure all ingredients are evenly cooked.
Pare -- To cut the skin from a good, usually with a short knife called a paring knife.
Pasteurize -- To kill bacteria by heating liquids to moderately high temperatures only briefly. 
Pastry Wheel -- A utensil with a cutting wheel attached to a handle. It's used to mark and cut rolled out dough, and may have a plain or decorative edge.
Piquant -- A term which generally means tangy flavor.
Poach -- To cook in liquid at or just below the boiling point. For eggs, meat, or fish, the liquid is usually water or a seasoned stock; fruit is generally poached in a sugar syrup.
Pulverize -- To reduce to a powder or dust by pounding, crushing, or grinding.
Puree -- To blend, process, sieve, or mash a food until it's very smooth and has the consistency of baby food.
Saute -- To cook quickly in a pan on top of the stove until the food is browned.
Score -- To cut shallow slashes into ham or other food, to allow excess fat to drain, or to help tenderize.
Sear -- To brown meat quickly over high heat. Meat may be seared under a broiler or in a skillet on top of the stove.
Steep -- To soak, in order to extract flavor or soften.
Truss -- To hold food together so it will retain its shape. Poultry and some roasts are often tied with twine or held together with skewers.

Cooking Hints & Tips: Microwave Shortcuts


Toasting Nuts -- Place 1/2 cup of nuts in a 2 cup measure. Microwave, uncovered for about 3 minutes or until toasted, stirring frequently.

Dry Bread Crumbs - Cut 6 slices bread into 1/2 inch cubes. Microwave in 3-quart casserole 6-7 minutes, or until dry, stirring after 3 minutes. Crush in blender.

Adding Salt - Do not salt foods on the surface as it causes dehydration (meats and vegetables) and toughens the food. Salt the meat after you remove it from the oven unless the recipe calls for using salt in the mixture. 

Blanching Almonds -- In a small microwavable bowl, microwave 1 cup water, uncovered for about 2-3 minutes or until boiling. Add 1/2 cup almonds to water. Microwave, uncovered for 1 1/2 minutes. Drain, rinse almonds with cold water. Slip off skins.

Peeling Tomatoes -- In a 2 cup measure, microwave 1 cup water, uncovered for 2-3 minutes or until boiling. Spear 1 tomato with a long fork. Submerge into hot water; hold about 12 seconds. Place tomato under cold water; slip off skin.

Cooking Hints & Tips


I found these at the front of a recipe book that someone gave me. Some of them are good old fashioned tips that seem like they could come from Grandma, but still pretty insightful. I just wanted to keep them handy... because you never know! 
  • Cream the butter: It is best to cream butter by itself before adding the sugar.
  • Chocolate Cake trick: When a chocolate cake requires greasing and flouring the pans, try using cocoa instead of flour. When the cake is done, there will be no white flour residue on your cake and it adds flavor.
  • Sticky spoons: Before measuring honey or other sticky ingredients, dip your spoon in oil. 
  • Moist Icing: Add a pinch of baking soda to your frosting and the frosting will stay moist and prevent cracking.
  • Smooth Icing: Dip your icing spatula in hot water and dry with a paper towel. The heat from the water will melt the oil in the icing making it smoother. 
  • Shiny crusts: For shiny pie crusts, brush the crust lightly with milk.
  • Frying: Never salt food to be fried -- it will draw moisture to the surface and cause spattering in the hot oil.
  • Cooling Rack: Use double-thick paper towels to place over cooling rack to keep the rack from making imprints into the cake while cooling.
  • Moist Cake: To make any home-made or boxed chocolate cake recipe moist and fluffier, add a spoonful of vinegar to the dry ingredients. You'll be amazed at the difference. 
  • Low-Fat: Apple sauce is a great fat substitute for low-fat baking. Simply substitute half the fat in a recipe with an equal measure of applesauce.
  • No Germs: Disinfect your kitchen sponges by placing them in the microwave for 60 seconds.
