My recipe is pretty informal-
3/4 cup sourdough starter
1 cup water
2 cups flour
Autolyze rest 25 min
1tsp salt
Mix, add flour til not sticking to mixer
Bread hook 8-10min
Rise 2-3hrs folding over every 30-40 min
Refrigerate overnight
Form/warm in basket 30-45 min
Bake 45 min @450f in dutch oven, lid off after 30 min
OH! also, you need to do equal parts by weight since flour weighs way less in volume than water you will have 120+% hydration starter and it won't grow!
