Ingredients for Miso Paste
- 1 cup of soybeans
- 1/4 cup of koji rice (or barley koji)
- 1/4 cup of sea salt
- 1/2 cup of water, plus more for soaking
Ingredient Notes and Substitutions
- Soybeans: Used for their protein and creamy texture. Substitute with chickpeas for a different flavor profile.
- Koji rice: This fermentation starter is essential for flavor. You can use barley koji or skip it, but the flavor will differ.
- Sea salt: Enhances flavor and aids in fermentation. Table salt is an option, but it may alter the taste slightly.
- Water: Hydrates and blends ingredients. Filtered water is best for purity, but tap water works fine.
How to Make Miso Paste
Step 1: Soak the Soybeans
Place the soybeans in a bowl and cover them with water. Let them soak for at least 8 hours or overnight to soften.
Step 2: Cook the Soybeans
Drain the soaked soybeans and transfer them to a pot. Cover with fresh water, bring to a boil, then reduce heat and simmer until tender, about 1 to 2 hours.
Step 3: Blend the Soybeans
Once cooked, drain the soybeans again. Using a food processor or blender, pulse them until they form a smooth paste, adding a little water if necessary.
Step 4: Mix in Koji and Salt
Transfer the blended soybean paste to a mixing bowl. Stir in the koji rice and sea salt until well combined, ensuring even distribution.
Step 5: Pack into a Jar
Using a spatula, pack the miso mixture into a clean glass jar. Push down firmly to eliminate air pockets, which can spoil the paste.
Step 6: Cover and Ferment
Cover the jar with a clean cloth or lid, allowing air to flow while keeping contaminants out. Set it in a cool, dark place for 6 months to ferment.
Step 7: Check for Fermentation
After 6 months, check the paste for flavor and texture. It should be smooth, creamy, and have a deep umami flavor.
Step 8: Store and Enjoy
Once fermented, transfer the miso paste to a clean container and refrigerate. Use it in soups, marinades, dressings, or any dish that needs a flavor boost.
Pro Tip: The longer you ferment, the richer the flavor. Just be patient!
