Final answer:
Cleargel, unlike other thickeners, can withstand high temperatures and acidic conditions, making it suitable for canning and pie fillings without losing consistency.
Step-by-step explanation:
One difference between Cleargel, a brand name for modified corn starch, and other thickeners is its ability to withstand high temperatures and acidic conditions without breaking down. This makes Cleargel particularly effective for canning and for making pie fillings, where the heat and acidity could affect other thickeners like flour or regular cornstarch, causing them to break down and result in a runny consistency. Cleargel provides a smooth texture and remains stable upon cooling, which is important for achieving the desired consistency in such applications.
