Humble House Sourdough Bread Starter Kit 1/2 Gallon Sauerkrock Open Ceramic Crock with lid 2 Liter Large Capacity 64 Ounce Jar, Made in America
Humble House's 1/2 Gallon Sauerkrock open ceramic crock with lid, a 2 Liter and 64 Ounce American-made starter vessel.
A sourdough baking crock is a lidded stoneware vessel built to do one job well: turn a proofed boule into a crusty, bakery-style loaf. Like a Dutch oven, the crock traps the steam your dough gives off, holding the crust supple through the crucial first minutes of rise before it sets crackly and deep brown. Because many crocks are made from unglazed or partially glazed stoneware, they breathe a little differently than metal, which some bakers feel gives a gentler, more even crust. Size, lid fit, and how easily the base loads all vary. Below we compare the sourdough baking crocks that trap steam reliably and give home bakers a repeatable artisan crust.
