My two are:
Making sourdough. I personally always heard like this weird almost mysticism around making it. But I bought a $7 starter from a bakery store, and using just stuff in my kitchen and cheap bread flour I’ve been eating fresh sourdough every day and been super happy with it. Some loafs aren’t super consistent because I don’t have like temperature controlled box or anything. But they’ve all been tasty.
Drawing. I’m by no means an artist, but I always felt like people who were good at drawing were like on a different level. But I buckled down and every day for a month I tried drawing my favorite anime character following an online guide. So just 30 minutes every day. The first one was so bad I almost gave up, but I was in love with the last one and made me realize that like… yeah it really is just practice. Years and years of it to be good at drawing things consistently, quickly, and a variety of things. But I had fun and got something I enjoyed much faster than I expected. So if you want to learn to draw, I would recommend just trying to draw something you really like following a guide and just try it once a day until you are happy with the result.
Cooking is much easier than it looks. Recipes are just suggestions and after looking at enough of them the commonalities to play around with it
Except baking. Unless you exactly know what each ingredient does.
Never baking. That is different from cooking
Baking is about ratios. You absolutely can mess around with baking even if you don’t really know what to do, you just can’t mess up the ratios - and I mean liquids/wet ingredients, dry ingredients like flour, then eggs and of course the important baking soda/powder.
Like regular cooking, once you get a good feel, you can do a lot.
It won’t let you make your own recipe, though. That does take a level of knowledge above just substituting or changing an ingredient or two.
