King Arthur Flour Unbleached All-Purpose Flour – 10 lb Bag

This is the flour I reach for most often. I buy the 10-pound bag because I go through it quickly once the weekly baking rhythm is going. Unbleached, never bromated, and milled to tight standards — it’s the kind of pantry staple that just works without surprises. If you’re building your starter, baking loaves, or making cookies, this is a solid, no-fuss flour that earns its place on the shelf

Why it earns its place

This is the flour I reach for most often. King Arthur’s Unbleached All-Purpose Flour is consistent, reliable, and strong enough for sourdough while still versatile enough for everyday baking. With an 11.7% protein content, it performs beautifully in the recipes from Flour Water Salt Yeast and anything else that calls for all-purpose flour.

How I actually use it

Building starters and baking loaves!

What to know before you buy

There are definitely other flours — local or regional mills — that can make excellent sourdough. If you’re lucky enough to have one nearby, check the protein content and make sure it’s at least 11.7%. King Arthur’s advantage is simple: it’s available nationwide and you'll never have trouble finding it.
