Combine in pot and heat over medium-low heat:
1 can Evaporated Milk
3 cans Water
In a separate small mixing bowl combine:
1 cup Sugar
4 Tbsp Cocoa
Add just enough water to the sugar and cocoa to create a paste. Stir ingredients together with a fork.
Add sugar mixture to pot and stir occasionally until chocolate milk reaches desired sipping temperature. Add 1 tsp. Vanilla before serving. Stir and enjoy. Try adding flavored extracts for a more gourmet taste.
