Clear Jel is a type of modified cornstarch that can withstand a wide range of temperatures, resulting in a thick canned pie filling that doesn't change consistency easily.
When you freeze Clear Jel, it’s less likely to separate or curdle when you take it out of the freezer to thaw, so you don’t have to worry about it being watery.
To use it in your pie filling, all you have to do is mix equal parts Clear Jel and water. The measurement is typically 1 to 5 tablespoons, depending on the fruit you’re using.
Whisk the mixture together until it’s well combined, and then toss it into your fruit pie filling mix on the stove. Once bubbles start to form, take it off the heat.
