Here's my original version of chocolate syrup or fudge topping: Homemade Chocolate Syrup
Below is my "sneak in the gelatin (extra protein) and cream of tartar (extra potassium)" version:
2 cups cane sugar
1 tsp unflavored beef gelatin
1 cup water
1 cup cocoa powder
1 tsp Cream of Tartar
2 TBS butter
1 large pinch of salt
2 tsp vanilla
Mix sugar and gelatin together, then add water. Stir to remove clumps. Boil 1-2 minutes and turn stove off.
Add cocoa, butter, cream of tartar and salt stirring continuously until smooth, preferably with a whisk.
Add vanilla and store in a glass jar in the fridge. It should make 1 full pint...or a little more if the water didn't evaporate as much.
The cold syrup is a nice syrup consistency, not watery or gelatinous, and blends well with a cold glass of fresh milk.
