Just a quick note about copyright and recipes...
"Mere listings of ingredients as in recipes, formulas, compounds, or prescriptions are not subject to copyright protection. However, when a recipe or formula is accompanied by substantial literary expression in the form of an explanation or directions, or when there is a combination of recipes, as in a cookbook, there may be a basis for copyright protection."

"How do I protect my recipe?
A mere listing of ingredients is not protected under copyright law. However, where a recipe or formula is accompanied by substantial literary expression in the form of an explanation or directions, or when there is a collection of recipes as in a cookbook, there may be a basis for copyright protection. Note that if you have secret ingredients to a recipe that you do not wish to be revealed, you should not submit your recipe for registration, because applications and deposit copies are public records."
"U.S. copyright law addresses recipes, but what holds sway can be called either ethics or etiquette. Cooking is not considered inventing; rather, it evolves. Copyright law specifies that "substantial literary expression in the form of an explanation or directions," such as a cookbook, can be copyrighted but that a mere list of ingredients cannot receive that protection.
The ethics guidelines of the International Association of Culinary Professionals focus on giving proper attribution to recipes that are published or taught. The association advises using the words "adapted from," "based on" or "inspired by," depending on how much a recipe has been revised. ("Adapted from" is the phrasing favored by The Washington Post and many other newspaper food sections, which, along with culinary instructors, enjoy "fair use" of someone's creation for the purpose of teaching, news reporting, scholarship or research.) The only time a recipe should be printed without attribution, the association contends, is when it has been changed so substantially that it no longer resembles its source."

I used to create recipe post cards for a greeting card company and had to be "up" on all the copyright stuff. What this basically means is a list of ingredients can not be copyrighted. The DESCRIPTIONS and DIRECTIONS that go with it ARE subject to copyright.
