Red miso paste, a key ingredient in Japanese cuisine, is a fermented soybean paste renowned for its robust, savory flavor and deep, earthy tones. Miso production involves blending cooked soybeans with rice, barley, or other grains that have been cultured with a specific mold called Aspergillus oryzae; the mixture is then left to ferment for an extended period. The red variety, or "aka miso," is aged longer than its counterpart, white miso, giving it a richer taste and darker coloration suitable for hearty dishes.
Home cooks and consumers will find red miso paste particularly useful across a range of flavorful dishes, such as soups, marinades, dressings, and glazes. The most iconic application of miso is for a Japanese staple—miso soup—which gains an umami depth from red miso. Incorporating red miso paste into a variety of recipes can add dimension and an alluring boldness to your home-cooked meals.
