Do you go by cook books or recipes handed down from family and friends?

I enjoy the recipes handed down more, but one of favorite cookbooks is the 4 ingredient cookbook. Talk about saving time! When we have church dinners, we have wonderful desserts with ingredients you might not think about like 7-UP or Mountain Dew. Do you go by cook books or recipes handed down from family and friends?
I use both. Sometimes I buy cook books just to have a good read. My favorite recipes have stood the test of time, and have been handed down for generations.Do you go by cook books or recipes handed down from family and friends?

I use both and also like to create my own. I've just configured a recipe for roasted ranch potato wedges!
I use both.
I do a little of both. And there are some things I've cooked for years and just do it automaticly.
