What are some extremely easy things you make from scratch?

I was so surprised how EASY pesto is to make. You don’t even have to cook it!

I will never buy salad dressing again, because that’s very easy to make too. I also make all my own seasoning mixes that they usually charge silly amounts for at the grocery stores.

I’ll share some of my recipes in an answer, but I was wondering what everyone else makes from scratch that is barely more effort than buying it premade.
