What is a more common alternative to isinglass? I was thinking pectin but can someone confirm? Thanks!

Other alternatives, depending on the pudding: arrowroot, cornstarch, agar agar, instant tapioca. The use of each is discussed at the websites below. http://www.foodsubs.com/ThickenGelatins.html http://www.foodsubs.com/ThickenStarch.html Sun Apr 01 18:31:03 -0700 2007 2440902 18222 maria lorraine
