What Is Miso?

A common component in Japanese cooking is miso. It is a salty paste that is brown or beige in color and is utilized similarly to a solid form of the well-known soy sauce. Japan has been using miso for more than 1300 yeCommonly Asked Questionsi” flavor and is salty.

Soybeans are boiled and pureed in traditional miso. Along with salt, koji—a magical ingredient—is added.

Fermented rice with plenty of enzymes is called koji. Soybeans are transformed into miso by koji. This is a gradual process that may take many months or even years.

Red, yellow and red miso paste

Miso comes in several kinds, each with a unique fermentation duration. For instance, white miso may be prepared in about two weeks, whereas red miso typically requires 11 months of fermentation!

To alter the flavor profile, you may also add other ingredients, such as seaweed, mushrooms, buckwheat, and chickpeas.

Why Consume Miso?

One common Asian component is miso. These days, people value it for both its flavor and health advantages. Although it is well-known from the renowned miso soup, you may use it anyplace soy sauce or salt are used!

The Miso’s Flavor

The two primary flavors of miso are umami and salty.

The sixth flavor, umami, is a mouthwatering taste that entices you to keep eating. Actually, the Japanese term for “umami” means “tasty.”

As a result, miso has a flavor that is complex and is used in cooking to give meals depth and “flavor.” For instance, it gives the broth of miso soup more personality.

It enhances the flavor of marinades. It enhances the flavors of the meat and vegetables in a meal.

The Advantages of Miso

Miso is very digestible even though soybeans are used to make it. Soybeans undergo fermentation, which also eliminates the antinutrients they contain. (ref)(source) contains a lot of readily digested intact proteins.

In addition, miso is packed with minerals and vitamins, such as zinc, manganese, potassium, and vitamins B2 and B1(source)ef)

Miso, like other fermented foods, has probiotic microbes that may strengthen the immune system and improve health. The microbiota and digestion are also aided by the nutrients and enzymes found in miso(source)f)

The advantages of miso on blood pressure, radiation resistance, and cancer prevention are also being studied. (ref)

What You Need to Make Miso Paste

There are only four essential components in our classic miso preparation.


Aspergillus oryzae mold has invaded rice or grains, resulting in koji. It is a necessary component in the creation of miso.

The most popular koji for making miso are those made from rice and barley.

To get koji, there are two ways to do so:

  1. Grow miso koji culture to cultivate your own koji.
  2. Purchase pre-prepared, dehydrated koji.


The most popular kind of legume is soybean, but you may also use chickpeas, yellow peas, or any other source of protein.

The soybeans should be cooked until they break easily between your fingers, after soaking them for the whole night.


In order to direct the fermentation process, salt is necessary. The desired kind of miso and the length of the fermenting process might affect how much salt is used.

There should only be one element in salt: salt. The addition of iodine or anti-caking chemicals to table salts may modify the flavor of miso.


Not present in the other components is a colony of microorganisms present in prepared miso. Although we don’t need it, adding a little amount of prepared miso enhances the chances of success and speeds up the fermentation process.

Tools for Preparing Miso

The weight and fermenting jar are important components in the lengthy miso fermentation process.


For miso fermentation, glass, food-grade plastic, wood, and stoneware are the best materials.

Make sure the fermentation jar is twice as big as the amount of miso paste inside. It is also simpler to pour the miso into a jar with a wide mouth.

The Crazy Korean Cooking fermentation containers and the 1 gal fermentation jars are two great options.

Weighing and Weight

The miso has to be crushed under a significant weight in order to be kept in an oxygen-free environment. The paste’s liquid and the fermentation gasses will climb to the top due to this weight. It is advisable to use a weight of 1 to 1.5 kg per kilogram of miso.

There are several choices:

  • A freezer bag containing beads, ornamental pebbles, or salt
  • Weights made of ceramic
  • Glass balances
  • A little dish and few water bottles
  • Weigh the pebbles (clean in a freezer bag) and the Crazy Korean Cooking container.

Frequently Asked Questions

What Distinctions Exist Between Soy Sauce and Miso?

Two typical Japanese fermentations are soy sauce and miso. Legumes and koji are employed in both instances. However, soy sauce is made using a different method.

Miso is a thickened soy sauce substitute used in cooking.

Can Koji Be Used to Make Miso?

No. Without koji, miso is not feasible.

Other fermented soybean pastes exist without koji, but they need a more involved procedure including natural microorganisms.

Get some dehydrated koji instead of attempting to make it at home. The simplest method to get started is this.

How Can White Miso Be Made?

White miso, also referred to as sweet miso or shiro miso, has a mellow flavor and is somewhat less salty than other types of miso. It’s salty, yet there are also undertones of sweetness and flowers.

Increase the koji and reduce the salt a little bit to produce white miso at home. Less than a month is needed to prepare white miso.

A Little White Miso Recipe
Use the normal miso recipe as a guide, but substitute the following component amounts to produce white miso:

  • 350g or 1.5 cups of dry soybeans
  • 4 cups (1000g) of koji rice
  • 80g, or 1/4 cup, of salt

Give it three to four weeks to ferment.

When Does Miso Ferment?

if you’re able to wait!

With time, miso acquires depth and flavor. It gently caramelizes, changing color and becoming deeper and darker.

  • Two weeks (white miso): There is a noticeable soy flavor. The koji’s flowery flavor is also detectable.
  • Three months: Tastes begin to emerge, with salty remaining the predominant flavor.
  • After five months: The flavor is not as complex as mature miso.
  • Nine months: The miso begins to darken and caramelize.
  • After a year: Miso has a lovely richness and the flavor that is sought.
  • Two years and beyond: Miso will become stronger and more umami-concentrated the longer you let it mature

How Can I Determine When My Miso Is Ready?

Taste your miso to determine when it’s done!

Should you discover that it requires many more months for perfecting, return the weight and disregard the jar in the cabinet.

How Do I Proceed If My Miso Has Mold?

Yeast or mold may eventually grow on the miso’s surface. On the other hand, yeast, mold, and oxidation are safe.

Remove and dispose of the gray coating and anything questionable from the miso’s surface. As you go, wipe off the jar’s edges. There’s a layer of miso underneath the surface that hasn’t come into touch with air, so it should taste and smell excellent. Have faith in your gut!

If there are visible spots of mold in the miso, this is most likely the result of improper jarring, which left big air bubbles in the product. You will unfortunately have to toss it away since there is nothing you can do about it.

How Do I Handle a Dry Miso?

Your miso may eventually become less watery if it was fermented in an atmosphere that was a little too warm. You may add a little water and mix well before eating it to acquire the right texture.

What Happens If My Miso Has an Acidic or Alcoholic Smell?

Miso may smell peculiar, particularly when it’s first fermenting. These odors are often the result of either too little or too much water in the combination.

Occasionally, the solution lies in simply extending the miso’s fermentation period. Verify that the miso has an adequate weight.
