Fudge with Cocoa

Sugar (granulated),2 cups
Milk,½ cup
Cocoa,4 tablespoons
Butter,1 tablespoon
Flavoring (vanilla),1 teaspoon

Betsey melted the butter in the saucepan first, then added the cocoa gradually, and when it was very smooth included the sugar and milk. These she let boil until a little of the syrup dropped in cold water formed a soft ball, then removing the saucepan from the fire, she placed it in a pan of cold water, added the vanilla, beat the fudge until it was thick like heavy cream, and poured it in the buttered pan and marked in squares.
