To culture the best, most versatile starter for the Krustic baker, we partnered with the legendary team at Spice & Zest to handcraft a two-flour culture. It combines whole wheat and AP flours to re-activate quickly, produce beautiful flavor, and enable you to bake any loaf with any flour from supermarket shelves.

• Authentic, multiyear wild yeast culture
• Cultured to rise true artisan sourdough
• Pure, complex, naturally fermented
• Just revive, feed, bake, and enjoy
