<<Disclaimer: Verify this information before applying it to your situation.>> Hi! I recently submitted a post asking for an earlier recipe for an angel food cake mixed (dry) with a canned lemon pie filling--Comstock brand. I have had many requests for the recipe, which was not mine originally, but which I sent in to satisfy all the requests. However, among the other Emails on the subject, I received one from a man whose address I seem to have lost. Sorry. He said he had heard that the canned Comstock pie filling is NOT GF. So i called Comstock this morning and was told the modified food starch is derived from CORN; all their canned pie fillings are GF. However canola oil is listed as an ingredient. it does not bother me but you should be warned. Read the label carefully. Naomi in Atlanta
