I'm trying to learn that myself. Thankfully one good thing with the world wide web is we have near unlimited access to "classes", with videos for nearly anything you can imagine wanting to learn. Down side (for me) I learn better hands on, and I need to ask the questions right away while working on it.
My husband once asked his mom for some recipes, she just gave him a blank look and said "I can't. It's all up here" pointing to her head. Thankfully she did write many down through the years (I think she forgot about them), sadly other family members helped those recipes cards grow legs and walk away through the years. Hubs finds recipes sometimes in older cookbooks and says "Mom use to make that" so I give it a go. A few have been winners and "even better" She went Home a few years ago (she was in a nursing home, so at least it happened before Covid) We made some of the copy cat recipes for my father in law. The look on his face while reminiscing............
PRICELESS.
The recipes I use the most I am trying to get gathered and at least written/saved on a memory stick/card. I'd like to start taking photos as each fave meal is made to put into a book for my kids along with the recipes.
