Miso Paste

Miso paste is a traditional Japanese condiment made from fermenting soybeans, koji, and salt. It adds a complex and unique umami flavor not only to miso soup but also to dressings, stir-fry sauces, and various dishes.

Recipe Ingredients

You’ll need the following ingredients to make this White Miso Paste Recipe:

White miso pate ingredients list.
  • Soybeans: Use dried soybeans. Large soybeans with thin skins work well for making miso. This recipe uses Toyomasari soybeans from Hokkaido, a popular choice for their high quality.
  • Rice Koji: There are two types of koji—dried and raw. This recipe uses dried rice koji. You can find it at Japanese or Asian grocery stores or sometimes in health food stores.
  • Salt: Refined salt produces a sharp and light miso, while mineral-rich sea salt creates a fuller and more flavorful miso. Choose the salt that best suits your preference.

Koji

Koji is an essential ingredient for making miso, soy sauce, and Japanese sake. It creates different enzymes, including ones that break down proteins (proteases) and starches (amylases). These enzymes help ferment and age the miso to give it a delicious flavor.

“Koji” is produced by cultivating the mold known as koji-kin (Aspergillus oryzae) on grains like rice, barley, and soybeans. For example, if the mold is grown on rice, it’s called rice koji. In making miso, rice koji, barley koji, and bean koji are all utilized.

Equipment

Here are some handy and essential tools for making miso paste.

  • Pressure Cooker: Use it to boil soybeans and significantly reduce the cooking time. If you don’t have it, cook them in a regular pot for about 1 hour until tender.
  • Yogurt Maker: A yogurt maker speeds up miso-making by applying high heat to accelerate fermentation. If you don’t have one, leave the miso mixture in a cool, dark place and ferment naturally for about a week.
  • Food Processor: Make the miso into a smooth paste using a food processor after fermentation.

Recipe Tips

  • Soak dried soybeans overnight to soften them. This makes it easier to cook and mash smoothly.
  • Mash the soybeans while they’re still warm for a smoother texture. You can also use a food processor if you want a very fine texture.
  • Make sure all tools, bowls, and containers are clean to prevent any unwanted bacteria. This helps ensure a safe and successful fermentation.

Storage

After fermentation, transfer the white miso paste to an airtight container and refrigerate. Try to use it within 2 months. You can also store miso in the freezer; it won’t freeze solid but may become slightly firm, so you can still easily scoop and use it.

Equipment

  • Pressure cooker
  • Food processor
  • Yogurt Maker

Ingredients

Instructions

  • Soak the Soybeans: Place the soybeans in a large bowl. Cover them with plenty of water and let them soak for 8 hours or more. They should double in size.
  • Cook the Soybeans: Drain the soaked soybeans and transfer them to a pressure cooker. Cover with fresh water, close the lid, and cook over medium heat. Once the pressure cooker reaches full pressure, turn off the heat and allow it to cool naturally until all pressure is released. Drain the cooked soybeans, reserving about 1 cup of the cooking water.
  • Make Soybean Mixture: Mash the soybeans using a masher until smooth. Add the ½ cup of reserved cooking water, koji, and salt. Mix thoroughly until all ingredients are well combined. If the mixture feels too firm, add a bit more of the reserved cooking water.
  • Ferment: Transfer the soybean mixture to a container that fits inside your yogurt maker. Set the yogurt maker to 60°C (140°F) and ferment the mixture for 8 hours.
  • Store: After fermentation, transfer the mixture to a food processor and blend until fully smooth, as the rice koji may not be fully broken down. Transfer the miso paste to an airtight container and store it in the refrigerator.

Notes

  • Soak dried soybeans overnight to soften them. This makes it easier to cook and mash smoothly.
  • Mash the soybeans while they’re still warm for a smoother texture. You can also use a food processor if you want a very fine texture.
