The 27-Layer Cold Lamination

We fold cultured French butter into cold yeast dough over three days. Butter sheets are maintained at 14°C to prevent melting, creating 27 microscopic alternating layers of fat and dough that explosively puff into airy flakiness when baked.

Pillar 02 • Sourdough

14-Year Mother Levain Culture

Fed twice daily with local stone-milled rye. Our culture harbors wild microorganisms indigenous to New York and San Francisco, developing delicate lactic sweetness and earthy depth without harsh vinegar sourness.
