Julia Child - Mastering the Art of French Cooking - OK for Kosher?
I think you should take it out from your public library and take a good in depth look at it. This way you don't have to buy it and you can look at all the recipes. If you see enough recipes in there that you don't have to change, or just have to change minimally, then you can justify buying it. If your library doesn't carry it you could either get an interlibrary loan from another library somewhere else or you can always request if from them. Most libraries are really good about buying books (cds, dvds, etc).
