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 work at an events company, basically, in the back office but have worked some events - I get the appeal. Hospitality is grueling work but satisfying work, your customers are right in front of you and you are making them feel better about themselves (in our particular industry), or feeding them and also just pulling off such a ridiculously difficult task, nearly everything going right, it's amazing. And when I did work at a restaurant, I also enjoyed being part of the customers' going out night, right? You are there, building that experience, also getting an experience.
My husband doesn't get it really but I do - if I had fuck you money I would open a bar, with a dinner night each week as an event.
I enjoy home cooking and hosting parties too. Hospitality really is a human sort of endeavor and it is satisfying to make people feel good and comfortable.
