Hello all. I could not find much info on why taffy doesn't work out, so I decided to join a forum. Here is my recipe for salt water taffy: 1 cup sugar 1 tablespoon cornstarch 2/3 cup light corn syrup 1 tablespoon unsalted butter + extra for buttering a baking dish, your hands, and scissors 1/2 cup water 1/2 teaspoon salt I mix the sugar and cornstarch, then add the syrup and water, then the butter and salt when done boiling. I am reading mixed messages as to how to increase the temp to 260...should I boil for a while, then reduce the heat? When can and when can I NOT stir? Many different ideas out there! My first batch was a success. For about a week, we had soft yummy taffy to nibble on. Then, this taffy became tough on the inside. Not really crunchy or hard on the outside. Alas, the last 2 batches would not "set". I pull and pull for 30 minutes, though the taffy never lightens in color, or becomes more difficult to pull. I know what it is supposed to look like, and these batches are not going that way. I wonder what I am doing wrong? Any ideas would be great.
