I love answering your questions!
Great answers to great questions! I want to share my answer for question 2, since it’s something that I’ve grappled with for years - how to remember what I’ve made in the past so I can make it again in the future. Several years ago, I started keeping a dinner journal. After dinner, I write what I served and where the recipe came from (which cookbook, website, etc). While not super-efficient, it’s helpful. I can look back thru my dinner journal to see which pizza dough recipes I’ve used (and repeated - meaning they were a hit!), and I can see trends and meal combinations. I’m still trying to figure out another way to index cookbook recipes that I love (and I have hundreds of cookbooks), but the dinner journal is a good starting place which requires minimal effort.
