Imitation vanilla is made by soaking alcohol in wood with vanillin, then it is extracted and chemically treated to taste like vanilla. Yep, thus I will stick to vanilla extract from now on since I love my family, lol.
Everytime I use gelatin my stomach turns. Once I found out what was inside jello I was never able to eat it again. I use gelatin, knox, to make my some of my fondants and gumpaste recipes. I was a vegetarian and this is how i found out about my previous beloved jello, lol.
