How to make Miso Paste
About recipe
Miso is a traditional Japanese fermented seasoning made from a combination of soybeans, koji (cultured grains), and salt. The process of fermenting these simple ingredients results in a rich and complex paste that has been a cornerstone of Japanese cuisine for centuries.
Homemade miso offers a unique depth of flavor and nutritional benefits that are difficult to match with store-bought options. The fermentation process not only enhances the taste but also produces probiotics, which can support gut health and digestion. By making your own miso, you can customize its flavor profile—from sweet and mild to robust and salty—based on the fermentation time and ingredient proportions.
Miso paste is incredibly versatile and can elevate a variety of dishes:
- Soups: Use it to create the iconic miso soup or enhance broths for ramen or stews.
- Marinades: Mix miso with ingredients like soy sauce, mirin, or ginger to create flavorful marinades for vegetables, tofu, or fish.
- Dressings and Sauces: Incorporate miso into salad dressings, dipping sauces, or even pasta dishes for a savory umami boost.
- Spreads: Blend miso with butter or tahini for a unique spread on bread or crackers.
By adding homemade miso to your cooking, you’re not just enhancing flavor—you’re connecting with a centuries-old tradition that combines the art of fermentation with the joy of cooking. Whether you’re exploring new flavors or looking to add healthy, fermented foods to your diet, miso is a must-have in every kitchen.
Ingredients / Makes 1kg of miso paste
- 400g of dried Koji
- 200g of soy beans
- 120g of salt
- Water: As needed
Instructions
- 1. Prepare the soybeans
- ・Before soaking, rinse the soybeans 2-3 times in clean water.
- ・Soak the soybeans in water for at least 12 hours (preferably overnight).
- ・After soaking, boil the soybeans in a large pot for 2-3 hours until they become soft. The soybeans should easily mash between your fingers.
- 2. Mix koji and salt
- ・Combine dried koji and salt in a bowl and mix thoroughly.
- 3. Mash the soybeans
- ・Drain the boiled soybeans and let them cool to around 40°C (104°F).
- ・Mash the soybeans using a food processor or masher. Adjust the texture to your preference, either smooth or slightly chunky.
- 4. Combine soybeans and koji mixture
- ・Mix the mashed soybeans with koji until evenly combined.
- ・Gradually add some of clean water as needed to achieve a soft, dough-like consistency, similar to earlobe softness.
- 5. Form miso balls
- ・Take portions of the miso mixture and form them into balls. This helps to remove air pockets.
- 3. Pack into the fermentation container
- ・Sanitize the fermentation container with alcohol spray.
- ・Firmly press the miso balls into the container, ensuring there are no gaps.
- ・Sprinkle a small amount of salt on the surface for added preservation. Cover with plastic wrap or baking sheet to seal the surface.
- 3. Add weights
- ・Fill a ziplock bag with salt and place it on top of the wrapped surface as a weight. Ensure the bag fits snugly between the surface of the miso and the lid of the container.
- 3. Ferment the miso
- ・Cover the container with a lid and store it in a cool, dark place for 3-6 months.
- ・Periodically check the surface for mold. If mold appears, simply scrape it off and continue fermenting.
- 3. Completion
- ・Once the miso has developed a deep aroma and rich taste, it’s ready to use. Transfer to a clean container and store in the refrigerator.
Tips
- ・Use clean water(tap water is fine) to avoid contamination.
- ・Keep the fermentation container sealed to prevent drying out during the process.
- ・Winter is the ideal season for miso preparation, as the colder temperatures reduce the risk of bacterial growth and enhance flavor development.
