Periodically I daydream about opening a gourmet food store (something similar to what the Barefoot Contessa was like before its demise). I'm a very good cook, and my foodstuff has garnered much praise from a wide mix of people, which does fuel this fantasy.
However, most of my recipes are from established cookbooks and chefs. Is using a recipe published in a cookbook for a business venture a form of plagarism? Are recipes protected by copyright laws?
So, I'm asking all the chefs and caterers and storeowners out there: do you routinely borrow other people's recipes or do you establish your own recipes (even if it's only changing one ingredient out of a long list, does that alone make it "your" recipe?
