Mix sugar, cocoa, flour, and salt in a heavy medium sauce pan. Add 1/4 cup or so of milk and stir to a paste. Stir in remaining milk and vanilla. Stir well to remove lumps and bring to a boil over medium-high heat, stirring. As soon as sauce comes to a boil, reduce the heat to low and simmer very gently for 5 minutes, stirring often. Cool and store in the refrigerator for up to 2 weeks, covered.

This is an old recipe for chocolate sauce to serve over scoops of ice cream, plain cake, or even a hot buttered biscuit. It's good!
Everyone loves chocolate sauce on their ice cream or other desserts. My visiting goddaughter loves the chocolate sauce, when she adds it to her warm milk in the morning for breakfast.
This chocolate sauce is supposed to be used for candy canes. I have never tried it on candy canes but wondered if it would work on pretzels.
This is a wonderful chocolate sauce! Love it warm over ice cream!
Mix until smooth chocolate pudding and karo syrup. Add peanut butter. Stir in half and half and vanilla until smooth. May need to thin with a little more half and half after it sits a while.
