- 4 TB/66 grams coarse sea salt (plus a little extra)
- 3 cans/650 grams canned cooked drained beans (see note below)
- 2 1/2 cups/567 grams rice koji
- 1 cup/245 grams bean liquid
Don’t obsess over the weights of things for this recipe. Just use the first figures given for each ingredient. Do not throw your bean water away. You need about a cup of it – a little over half of one of your bean cans full – and you need to follow the easy and exciting steps as we describe them. Ignore the words in italics below (they look slanted to the right) entirely if math stresses you out.
The important thing is that you get about 1 cup or 245 grams of the bean liquid and that you follow the order of the steps we describe. Otherwise, you will need more bowls, and most likely a scale. And something besides your hands to mix with. With the 3 cans of Brad's Organic salad beans that say 15 ounces on them that we used we ended up with about 5 1/2 cups or around 650 grams of beans, and a little more than two cups or 565 grams liquid from the beans. If you use brown rice or barley koji, you might need almsoit twice the amount of bean liquid. And more salt.
Any plastic bucket you use must be food safe, and cleanable if it looks dirty. It’s really easy to find these from a restaurant or other place that gets thick ones with food in them all the time. You can also order them online. If you are using a recycled container make sure it hasn’t been used for chemicals or bleach, or exposed to heat. The thicker the better. Make sure you don’t have a leaky bucket with tiny or obvious holes in it.
We always use coarse salt. Use coarse Kosher salt if you can’t get an only salt coarse sea salt like the red La Baleine container on the right. The fine La Baleine sea salt actually has several added ingredients. If you can get coarse Maldon smoked or regular coarse sea, or another brand that is just salt you can use that instead.
Don’t open the cans all the way. Keep the beans in the can when you drain off the liquid. When you remove the bag of koji from the container you will have a container to drain the liquid off the beans into the koji container. But keep the beans in the can.
If you are using beans with a pull off top – Goya organic, for example – don’t pull that top all the way off either. This is important unless you have other containers and a strainer you have already cleaned.
This is a recipe for a one bucket miso. You could use other beans like Eden brand black soybeans or yellow soy beans or garbanzo (ceci) beans, or whatever ones you find that don’t have preservatives or chemicals as long as they say organic.
Actually, beans with seaweed in them, or spicy beans also work unless you don’t want spicy miso. With certain beans like garbanzo beans just make sure to crush each bean between your fingers as you mix up the miso. This ensures that you really mix everything together well. Unless you are intentionally trying to make a country style, chunky miso, you really want to mash things up very well.
Let’s Get This Party Started Right
Take some of your bean water and swish it inside your bucket. Try to get it on the sides. Dump the three tablespoons of the coarse sea salt in the bottom of the bucket. Try to get as much of the salt on the sides but don’t get stressed about it.
Add all your koji. Start massaging it together. If you were using fresh koji it would break down really quickly, and even start to melt. Because we are using dried koji in this case, it might take longer for that to happen. Massage a minute, let it rest for two. Then massage a minute then let it rest for two. Again. Repeat.
After the frottage you should only have little bits of rice covered with enzymes, hungry for beans. Shove all the beans into the koji and salt mix and use your hands to prod the beans, forcing them to yield between your finger tips.
You should be able to start to make balls that start to hold together (see above). After about seven minutes, you’ll start to see splotches of beans, koji and salt that have stuck to the bottom or sides of your bucket. Let it rest for a few minutes if you must. Otherwise keep going.
The next day we added our cup of room temperature bean water. It’s okay if everything, including the bean water sat out, covered, for 12 hours or more. We put our bean bean water in the koji container into the miso container then cover the entire thing with our rags so nothing gets into either.
If it above 80F where you are making or storing your miso, sprinkle a little salt into your bean water. It’s likely your miso will be melding together at that temperature.
After rolling your balls of miso together you can start to pack them down with your hands into your container. The balls should hold together and feel firm, yet still pliable and yield. If they crumble, they are too dry and need a little moisture. If you have any bean water or just a tablespoon or two of clean water massage that into your miso before packing it down very firmly.
After your miso is well packed down sprinkle with at least 1/2 tablespoon of coarse sea salt. If it is 80F or higher, you can sprinkle up to an entire handful (one heavy tablespoon) onto the top. If you have a lid, cover it. Otherwise, start wrapping it with your rags.
Unless you will be making other misos just take a picture of this one and name the picture with the date and type of miso. Otherwise label it with a piece of tape and a marker or pens that doesn’t run. You can wrap it up even further if you like. Keep it out of direct sunlight. This could be ready in as little as ten days, or maybe two months if it started off and stayed cold for that time.
You can check on it at any time. Just untie the rags and take the lid off. After a few days it might have a slight smell. Let it air out a few minutes, mix it up again with clean hands and repack it in.
If there is a very strong smell, or some mold or yeast growth on top you’ll have to take that off and air it out at least an hour. We don’t recommend stirring that back in with a fast ripening miso like this. Add a little more salt.
If the miso is a little puffy or loose there is probably too much water in it. Add a teaspoon or more salt and repack. Check it in a few days.
