In both South Korean and Japanese cultures, they have a condiment made from soybeans. On one hand, in South Korea, they have doenjang. On the other hand, in Japan, they have miso. While both products are made from soybeans, are fermented, and are used in cooking, they are incredibly different. Here, we will explore the difference between the two! So, doenjang vs miso: what is the difference?

What Is Doenjang Paste?

Doenjang, known as soybean paste in English, is a type of fermented paste used in Korean cooking made from soybean and brine. In Korean eating culture, they use doenjang in many different ways. For example, doenjang can be mixed with other ingredients to be eaten as a condiment A popular mixed condiment is ssamjang, a dipping sauce served with Korean barbecue. Doenjang can also be used as the base in soups and stews, as well as a sauce for braising fish and meat. 

How to Make Doenjang (Doenjang Production Process):

The earliest records of soybean fermentation in Korea dates back to a time before the Three Kingdoms era. Known documents and writings about doenjang go back as far as the 3rd century A.D.

In Korea, people make soy sauce and doenjang during the same process. Actually, doenjang is the byproduct of making traditional Korean-style sauce sauce! To make doenjang, you start by making ‘meju,’ a soybean brick. First, the soybeans are soaked overnight. Then, they are boiled in saltwater before finally being pounded in a mortar or millstone. These pounded soybeans are then shaped into the meju soybean bricks and left to dry.

Once washed and dried, the meju bricks are placed in onggi crocks (jangdok). Then, brine and further ingredients are added to the crocks as well. After some time, once the brine and meju bricks have aged and fermented, the brinks are broken down into chunks to become doenjang. The brine is then boiled to become Korean-style soy sauce. 

So, with this style of fermentation, Koreans make two products they use in everyday cooking!

Doenjang Ingredients:

While the most traditional Korean doenjang uses only a few ingredients, the commercial and heavily processed versions use a lot of additives. 

Traditional Ingredients May Include:

  • Soybeans
  • Water
  • Sea Salt
  • Dried Chili Peppers; And
  • Dried Jujubes

Commercial Ingredients May Include: 

  • Soybeans
  • Water
  • Salt
  • Alcohol
  • Koji Starter; And
  • Wheat

If you want to buy commercially made doenjang, but are on a gluten-free diet, I recommend checking out our blog post for ‘Gluten-Free Doenjang Brands.’ There, we have lots of recommendations. You can find some of these recommendations below in my Amazon picks!

Unfortunately, there isn’t a soy-free substitute for doenjang at this time. 

Doenjang Flavor (What Does Doenjang Taste Like?): 

If you place doenjang on a spoon and take a bite, you will automatically taste salt. If you are unfamiliar with doenjang, you may not be able to detect any other flavor by itself. Doenjang really shines when combined with other ingredients and flavors. Once combined with other ingredients (such as with water as a soup base), you will find that doenjang tastes rich, savory, and earthy.

Honestly, there isn’t a comparable flavor in the Western culture. Finally, though also made from soybeans, Japanese miso does not taste anything remotely like doenjang. So, now that we have learned about doenjang, let’s learn the history, taste, and uses of Japanese miso! 

What Is Miso Paste?

Miso is a traditional Japanese paste made from fermented soybeans. The paste is used for sauces and spreads, as well as for pickling vegetables, braising fish and meat, and as a base in soups and stews. 

How to Make Miso (Miso Production Process):

Like doenjang, miso is made through fermentation. Though that is the case, the process of fermentation is quite different. To make miso, you go through a two-step process. The first step is making koji, a type of fermentation starter culture made using a grain such as rice, barley, and/or rye. Traditionally, to make koji, you must introduce the mold ‘Aspergillus oryzae’ onto your grain. The mold ferments creating the starter for the miso. Then, you complete the second step– add the koji to the soybeans and other ingredients to ferment and age. Letting everything ferment turns the soybeans into miso! 

The type of miso produced depends on the koji starter, the treatment of the soybeans, and the further ingredients.

Miso Ingredients: 

Miso can have a variety of different ingredients! These ingredients help define the type of miso being produced. The production of miso can include: 

  • Barley
  • Whole Wheat
  • Brown Rice
  • Chili Peppers
  • Hemp Seed
  • Buckwheat
  • Highland Barley
  • Millet
  • Soybeans; And So On… 

While doenjang keeps the same basic ingredients, the ingredients of miso changes depending on the type of miso desired. To learn all about the different types of miso, I recommend checking Nami’s blog Just One Cookbook! She has an in-depth article on the subject.

Many types of miso can be free of certain major allergens such as gluten. I enjoy and recommend buying the Hikari Organic Miso paste. They sell different types of gluten-free miso. You can find recommendations below in my Amazon picks!

Unfortunately, like doenjang, miso is a soy-based product and does not have a good substitute at this time. 

Miso Flavor (What Does Miso Taste Like?):

Like I stated above, the flavor of miso is dependent on the koji starter, the treatment of the soybeans, and the further ingredients. While some miso pastes taste incredibly sweet, others have a bolder and richer taste.

You can have miso that tastes sweet, fruity, earthy, savory, and so on… Just know, miso will always have a strong taste of saltiness from the aging, preserving, and fermentation process!
