Into your stand mixer or just a large bowl, dump in yeast, salt, warm water, and 1 cup of bread flour; allow to sit covered for an hour.

Start mixer, or use hands or wooden spoon, add 5+ cups flour mixing until dough comes away from sides of bowl.

Put dough into a large sweater size plastic container (trust me, the shoe size will be buried and your oven will be a mess!) into the cold oven, covered, no light, no hot water. Leave sit for 2 hours. Refrigerate.

I have to use the cold oven because my kitchen must remain cold but if your kitchen is toasty warm, counter top is fine to proof.
