This loaf is leavened solely with our Organic White Leaven. The flour in the leaven constitutes 30% of the total flour in the recipe. We use a combination of Marriage’s Organic Strong White Flour and Wildfarmed T65 White Flour to create a crusty loaf with an open crumb, indicative of extended fermentation. A 48-hour process is used where the shaped dough pieces in bannetons are retarded overnight before they are baked in the oven. Ingredients Marriage’s Strong Organic White Flour [WHEAT], Wildfarmed T65 White Flour [WHEAT], Salt.
