Recipes have been around for a very long time. According to Wikipedia the oldest known recipes date back to 1600 BCE. The problem is, historical evidence suggests that recipes were used long before that time, there just aren't any surviving recipes to prove it.
When I was in culinary school one of the instructors showed us a photo of a recipe that was supposed to be 2300 years old. That would put it right around 3 BCE.
What is interesting about old recipes, to me, is that they don't look like recipes do today. Typically they were a list of ingredients without any amounts, and no instructions. The theory being that the skill of the cook would determine the outcome of the dish.
If cooking food recipes and food history is of interest to you, You should check out Food Timeline. This link takes you to a food and recipe timeline listing when those things first appeared. In addition they have some old recipes listed in paragraph format, that are fun to look at.
