My other half wants me start doing it commercially, so she can sell it in her veg boxes, but I feel I need a hell of a lot more practice! Especially as it would mean having 5 to 10 loaves ready for the same day. Think I'm fine with it as hobby for a bit, but maybe something to aim at.
If tempted, go on a course. Seriously. Find a decent sourdough baker, and go on one of their one-day courses. Nothing else will skill you up that well. All the practice in the world can’t compare to a day (or so) being taught by someone who does it for a living.
I’d cheerily recommend our own organic sourdough nut, as his courses are beyond outstanding. He’s literally responsible for everything I currently do. But that’s Obvs the wrong side of the country.
5-10 loaves a day is, IMO, nuts. In a domestic oven. And to any form of baking routine / schedule. Whilst holding down a normal / additional job.
We have a single oven (ie, not a double, so bigger cavity) with a decent baking stone (which I’d say is necessary for decent oven spring). I can get 2*1kg done at a time (say, 40 mins). Or 1*2kg (say, 45-50 mins).
With a bit of self punishment, I can get two bakes done in a couple hours in the morning. That’s 4kg / 4*1kg. I couldn’t fit any more in.
I’d reckon on 5 bakes for 10 loaves. Or 5*45 (will become slower after the initial two!), = say, 3.5hrs (+1hr to cool) of constant attention for, say, £30? ingredients and electricity not included?
Might be possible to bake 4*1kg at a time. Even with an outstanding bread-focused £850 oven, id be worried about how that would turn out. Would certainly take longer, and the risk of an uneven / dodgy bake would be magnified.
So.. yeah. Idk.
It might be technically doable. But ime, may well result in a pitiful / sub minimum wage income from it. Unless you’re able to massively upscale.
(I’d want a new fridge, and probably +1 oven (if not a proper 8-12 loaf bread oven), and one helluva bigger dough beater before trying to go remotely actual-commercial). The prospect of beating 10kg of dough in 5*2kg batches is... almost too awful for words. It certainly wouldn’t be baking for love any more!
