Rulings on file
Gelatin is so thoroughly transformed from its source that it is no longer considered the forbidden substance. The CJLS accepts gelatin from any source as kosher and pareve.
Isaac Klein, "The Kashrut of Gelatin," Responsa and Halakhic Studies (1975)
Cheese made with rennet of any origin is permitted, since rennet is a dried, transformed substance used in minute quantity. Many Conservative Jews still prefer certified cheese; we note it either way.
Isaac Klein, "The Kashrut of Cheeses," CJLS (1969)
Rice, corn, beans and other kitniyot are permitted on Passover for Ashkenazim as well as Sephardim. Chametz (the five grains) remains forbidden.
Amy Levin and Avram Reisner, "A Teshuvah Permitting Ashkenazim to Eat Kitniyot on Pesah," CJLS (2015)
A reliable hechsher is the preferred way to establish that a processed food is kosher. Where none is present, the ingredient list is read against CJLS rulings and the result is marked for your judgement.
Rabbinical Assembly, "A Guide to Jewish Religious Practice" (Klein, 1979), ch. 21
Pork, shellfish and other forbidden species and their recognizable derivatives are not kosher.
Shulchan Aruch, Yoreh De'ah 79-83, as followed in Conservative practice
The CJLS permits wine produced without kosher supervision in most circumstances, while recommending kosher wine for ritual use. Grape ingredients are noted, not forbidden.
Elliot Dorff, "On the Use of All Wines," CJLS (1985)
