What is in miso paste?
Miso paste can be made of a selection of ingredients to achieve three types of miso. The basis of all miso paste is soybeans, salt, koji (fungus), and either rice, barley, or buckwheat (grains).
The essential ingredient in miso paste is Koji (Aspergillus oryzae), which is the Japanese word for fungus and mold.
Miso is a cultured food, dependent on bacteria and fermentation. The three main types of miso paste are:
- White miso – shinomiso – has a very light yellow color and a mild taste.
- Yellow miso – shinshumiso –yellow color and a stronger flavor than white – it is usually made with barley instead of rice.
- Red miso – akamiso – dark color – the most intense flavor, very salty and pungent.
In North America, there is also a fourth mini category called awase, which is a mixture of the white and the red miso paste.
The shelf-life of miso paste is at least one year, even more, if it is stored in the refrigerator, once opened.
The best way to store miso paste is in its original container in the fridge. Once you use it, place some plastic wrap over it to prevent oxidization.
Gourmet miso paste
Since there are so many varieties of miso, there are also some options that have added ingredients. Here are four popular miso varieties:
- Genmai miso: made with brown rice and has a nutty flavor.
- Soba miso: made with buckwheat and has a taste similar to yakisoba noodles.
- Mugi miso: contains only a little bit of grains, it has a higher concentration of soybeans.
- Dashi miso paste: this paste contains dashi in it, making it the perfect base for miso soup. You can make it without dashi stock, just by using this paste, adding hot water, noodles, and vegetables.
A brief history of miso
There is an ongoing debate about the exact origins of miso paste. Miso is, in fact, not a Japanese invention. A similar paste was first used in China in the 4th century.
It was made by mixing soybeans, alcohol, salt, and wheat and letting the mixture ferment.
The name ‘miso’ first appeared in written form in the year 800, and since then, it has become a common ingredient in many Asian dishes.
Miso migrated to Japan via Buddhist monks sometime in the 7th century. It is there that it became ‘miso’ as we know it today.
Some of the ingredients were changed, and the flavor was improved. The Japanese version of miso paste is the one that is most popular today.
What does miso paste taste like?
Most people agree that it tastes like umami – one of the five tastes or flavors in Japan, considered to be a “savor” taste.
When you first taste it, it’s going to seem salty, combined with a hint of tanginess, sweetness, and earthiness.
Depending on the intensity of the paste, it will taste either slightly sweet or very meaty and salty.
The texture is similar to peanut butter, some miso is very pasty and smooth, while some are chunky.
When cooking with miso, you only need a small amount because it’s such a savory and flavored food, a little goes a long way.
How is miso made?
The ingredients are left to ferment naturally for varying lengths of time. The longer the mixture ferments, the stronger the flavor of the paste and the darker to color.
The manufacturing process is quite simple:
First, the fungus (koji) must be made. You have to add some spores to a small portion of your grain and soybeans.
You can use steamed rice, mix it with the soy, and let the culture develop. The fungus will start to form, and the starch in the mixture will turn into sugar and glutamate.
This is what gives it that specific umami flavor.
The ingredients (grains, soybeans, salt, fungus, and any additional unique ingredients) are mixed and left to ferment for a period of a few weeks for light miso and a couple of years for very dark miso.
What foods do you use miso paste in?
Miso paste is most commonly used in soup. Miso soup is a very common dish in Asian countries and North America.
In Japan, it is a tradition to have miso soup for breakfast. Thus, miso has become a staple in Japanese households, restaurants, or for takeout.
The paste actually has many uses. Here is a list of the most popular types of foods you can add miso to:
- Noodle dishes
When you use miso paste, you want to make sure you never put the paste into boiling dishes. You want to add the paste into a dish at the end of its cooking period.
If you boil it too much, the heat will destroy the healthy bacteria and cultures of the miso, and you’ll be left without the health benefits of this paste.
