Most all-purpose flour is a commodity. This one has a story. Hayden Flour Mills stone mills a blend of White Sonora heritage wheat and high-protein Hard Red Spring wheat, both grown on their own farms in Arizona. The result is an unbleached, unenriched flour with real flavor — the kind that makes your cookies, pie crusts, and pizza dough taste like something. Jeff and Emma Zimmerman restarted the historic Hayden Flour Mills in Tempe, Arizona in 2009, reviving heritage grain varieties that had largely disappeared from American agriculture. Their mill runs on 100% solar power, and every bag is stone milled in small batches, never bleached or chemically treated. Substitutes 1:1 in any recipe.
