I made a low-yeast, overnight bread this morning. Well it started last night: a simple 500g flour/320ml water/0.25 tsp yeast/bit of salt dough, roughly mixed and kneaded a little, then rested for an hour, then book-folded three times with 30 minute intervals, then proved overnight in the garage (coolest place available), then book-folded once more this morning, shaped and put into a loaf tin, proved again in a warm place then baked.
It turns out with a close, springy structure not unlike a sourdough and a somewhat similar flavour (especially in the crust). It means I can have a fresh loaf ready for lunch without having to get up at the crack of sparrow’s. Plus it extends the yeast you may have available (I used dried).
