I thought I read in The Cake Bible.....the thing is corn syrup has h2o in it, unlike straight glucose. I thought it was about 1 T per c. ....that would throw off any sensitive recipe. And a recipe calliing for glucose is probably a non-sensitive recipe.
But if you made something like a flavoring syrup or then it's not a problem. I assume you follow....it depends upon the item being made.
In what recipe do you wish to make this substitution?
