Sourdough donuts
Used the recipe on Perfect Loaf, way too long to detail here but the ingredients are, for 18 of them (he always has these weird odd measurements like 101, I do often round them with no ill effect but will write them as the recipe states):
203 g very active starter 100% hydration
253 g all purpose white flour
253 g strong white bread flour
187g eggs - use extra yolk to adjust to this weight
101 g butter
101 g white sugar
91 g water
10 g salt
It takes a couple days to finish these (I start Friday midnight to get Sunday morning donuts) but most of that time is waiting not working).
Couple of notes- he says the final rise takes 12 hours but that must be in a cold climate, here in the subtropics it took about 7 to be perfect. And when he says careful attention to shaping he means it, but it's easy if you keep the dough chilled, with the butter in the dough it's not too sticky. Don't be afraid to really stretch it when forming the little dough balls, you want a tight surface all over. If you can shape buns, and your starter is robust, this is about a foolproof recipe.

I can't see the picture in the header, hopefully you can. Will put below too.

I would go with the second part of your message here and skip it UNLESS you are having symptoms and think there is really something the scans missed.
I actually had an incidental scan, was getting a "Coronary Artery Scan" because I've had always high cholesterol - it came back perfect, no buildup but they found benign little masses in my liver - doctor says absolutely normal and I understand why they would look (free knowledge for me) but I think I would be a little better off not knowing that.
