Authentic Homemade Miso
- 1 kg Soy beans
- 1 kg Koji (dried or fresh)
- 500 grams Salt
- 2 Red chili peppers (optional)
- Rinse the soy beans, then soak them in plenty of water overnight (for a 24 hour period).
- The soy beans will triple in size from rehydrating, so be sure to use a large pot.
- Here is what they should look like after soaking.
- Depending on the soy bean, scum may appear, but without removing the scum, set the pot to boil (do not refresh the water).
- Bring to a boil over high heat, then reduce to the lowest setting.
- Skim the scum and simmer until the soy beans can be slightly crushed between your fingers (this should take anywhere from 3 to 8 hours).
- This is how it should look after skimming off the scum from the surface.
- Do not bother to remove it too carefully; just skim enough to remove the majority of it.
- Test by crushing a soy bean between your fingers, and if it can be slightly crushed, turn off the heat, cover with a lid, then let sit overnight.
- Return the pot to heat and simmer for about 30 minutes over low heat.
- They are now ready to be turned into miso.
- Prepare the necessary ingredients and equipment: 2 bowls or pots, a 10-liter pickling tub, 2 large food-grade plastic bags, and a potato masher.
- While simmering the soy beans, break up the koji into small pieces, then combine with the salt.
- Line the pickling tub with a double layer of the food-grade plastic bags.
- Mash the soy beans (to your desired consistency) with a potato masher while still hot .
- Do not discard the boiling water from the soy beans.
- This is what the soy beans look like after they are mashed (I mashed them to a miso-like consistency).
- For easy mashing, use a meat grinder, if available.
- Once the soy beans have cooled to the touch, mix in the koji.
- Then, mix in the boiling water from the soy beans until the consistency resembles miso paste.
- Pack the miso into patties, as though making hamburger patties, while pressing out any air pockets.
- Slam the miso patties into the tub as hard as you can, and after several handfuls, press out the air and level the surface, then repeat.
- Level the surface while pressing out the air, and very lightly sprinkle with salt.
- To the extent possible, press the excess air from the inner bag and tie it closed with string.
- Place a drop lid on top, then weigh the miso down with a weight equivalent to the weight of the beans.
- If you don't have a weight, use a bag of salt.
- The key is to press down on the miso with substantial weight.
- Press out any air, and secure the outer plastic bag with a string.
- If you have red chili peppers, place them inside the outer bag to inhibit mold growth.
- You could also use shichimi (7 season chili spice mix) spice.
- Cover the outside of the bucket to prevent dust from entering.
- Store it in a cool, unheated environment.
- Every 2 months, stir it up, and taste until it reaches the desired degree of fermentation.
