Updated July 27, 20261 min readCited sources

Miso is a traditional Japanese fermented paste and seasoning made mainly from soybeans, salt, and koji. It is best known as the base of miso soup and is widely used in Canadian kitchens.

What it is

Miso is a thick, savoury paste produced by fermenting soybeans with salt and koji (a starter culture from Aspergillus oryzae). Some varieties include rice, barley, or other grains. The fermentation process can take weeks to years, giving miso a range of flavours from sweet and mild to deeply salty and umami-rich.

How it is used

Miso is most commonly dissolved in hot water or dashi to make miso soup, but it also appears in sauces, marinades, dressings, spreads, and pickling. It adds depth and savoury umami to dishes. In Canada, miso is a staple in many home kitchens and appears in fusion cooking and restaurant menus.

Why it matters in Canada

Miso is widely available in Canadian grocery stores and is used in both traditional Japanese cooking and local adaptations. Its popularity reflects the broader embrace of Japanese ingredients in Canadian food culture, from miso-glazed salmon to miso-based dressings.
