The signature Poilâne sourdough loaf is made from four ingredients: sourdough, stone-ground wheat flour, water and sea salt. Who knew something so simple could be so delicious! Baked in a wood-fire oven, this loaf is not something you can simply recreate at home. Focus on baking up some more banana bread at home and treat yourself with this Poilâne loaf which can be delivered directly to your doorstep, or of course, picked up from the bakery.
