I have an early 1990s Betty Crocker cookbook. It is not in any way great, but it tells how to cook a turkey or a baked potato or a few other things and then there are lots of beloved childhood dishes that, since my Mom wasn't some amazing chef, are pretty much straight out of the Betty Crocker Cookbook.
As far as online recipes, I just google whatever I want to make. If the recipe starts out with "I was born a poor black child..." and goes on for 37 more paragraphs before getting to actual food preparation I skip it. If there's more than about 5 ingredients and I have to drive around or order them instead of just going to the nearest supermarket I skip it. If there's 98 steps and farting around, I skip it. I'll usually be left with at least one recipe that isn't a pain in the ass and most of the ingredients are in my cupboard and what I lack I can substitute or safely skip.
