I have a database that I've called "food" and I'm a bit stumped on how to store the ingredients for a recipe. Should I create a separate table for the ingredients or just have the ingredients insert into the Recipe table as a comma-delimited list? Different recipes will not be using the "same ingredients" in that, they won't be sharing a value such as onion. If 10 ten different recipes have onions, then onion will be in the database 10 times (is that smart?).
