First, let me say that recently I have been testing a lot of thickeners and gelling agents. I have been looking for something clearer and cleaner than what has typically been available in the local grocery. After reading the description of Clear Jel I was tempted to forego this one. I am glad I didn't. This product is a modified corn-starch. What does 'modified' mean?? I don't know. And truth told, I don't really care too much. The real questions that need to be answered are, "Does it do what it is supposed to do?", "Does it do it better than a different, readily available product?" and "Is it a cost-effective alternative?" With those questions in mind, I made the purchase and have now done some testing.
