This sounds so delicious! Unfortunately I can’t eat taffy any more due to problems with my jaw, but if I could, boy-o!
2 cups brown sugar
1 cup white sugar
scant cup molasses
1/2 cup water
When it comes to a boil, add 1/4 tsp cream of tartar or 1 tbsp vinegar. After it has boiled a while, add a piece of butter a little larger than a walnut. Test with water at room temp. Cook to a hard wax. Just before taking from stove, add 1/4 tsp soda. Vanilla after it cools.
