What is Miso?

Miso is a deeply flavorful Japanese ingredient made by fermenting soybeans with salt and koji—a starter culture that transforms humble soybeans into a rich source of umami, protein, and probiotics. It's been a cornerstone of Japanese cooking for over a thousand years.

Once reserved for samurai and nobility, miso paste is now a versatile pantry staple that adds crave- worthy umami to everything from comforting soups to refined sauces. Whether it's the mild sweetness of white miso or the bold punch of red, there's a miso to enhance any dish. In this guide, you'll learn how miso is made, how to choose the right type, its many health benefits, and the best ways to use and store it.
