Fermented Black Beans
Intensely savory, salty, and earthy with a rich fermented depth; a small quantity adds a pronounced umami backbone to sauces and stir-fries.
Lens analyzedFermented black beans (douchi) are black soybeans that have been salted and fermented until intensely savory, soft, and deeply umami. A cornerstone of Cantonese cooking, they appear in classic dishes like black bean spare ribs, clams with black bean sauce, and mapo tofu.
Where it comes from
Fermented black beans, known as douchi, are among the oldest preserved foods in Chinese cooking and a cornerstone of Cantonese black bean sauce. North American cooks find them in vacuum bags or jars at Asian grocers, where they keep almost indefinitely in a cool, dry place.
Buying it
Look for plump, moist beans that are uniformly black and slightly glistening — dried-out, shriveled beans have lost flavor. The aroma should be pungent and savory, not sharp or acrid.
Storing it
Fermented black beans keep at room temperature in an airtight container for many months due to their high salt content. Refrigerate after opening for best flavor.
Keeps about 1 year in the pantry.
