<<Disclaimer: Verify this information before applying it to your situation.>> Dear Listmates, Well the Knox company has won hands down. All of the reponses that listed a brand indicated that Knox gelatin is GF. Several also explained where gelatin comes from. The following response (from Gladys) sums up the answers pretty well indeed. My Webster's dictionary says,"a tasteless, odorless mixture of proteins extracted by boiling skin, bones, etc." From what I understand it is usually from cow bones, etc. This would also seem to imply that any brand of gelatin is probably GF. But as always we should probably double check. It also implies that there is probably no such thing as a vegetarian gelatin (sorry Andrea). You may want to ask some baking experts re: whether you could substitute a fruit pectin (sure jello and certo are GF) for gelatin. I presume you would get different results so if it is possible to sub. I don't think it would be one for one. Thanks all. joan Ardmore, PA, USA
