Japanese Plant-based Protein

Both soybeans and koyadofu is great Japanese plant-based protein. Koyadofu is used as a substitute for meat in Japanese vegetarian cooking as it has a chewy texture. Let me give you a quick guide about koyadofu.

What is koyadofu>

Koyadofu is dried preserved food made by freezing tofu, aging it at a low temperature, and then drying it.

Since it’s made from tofu, it’s a soybean product known for its high nutritional value, such as protein, calcium, and dietary fiber.

When you cook it, it’s required to soak in the water and become like a sponge. It’s soft, chewy and flavorless.

The most traditional dish is “simmered koyadofu, ” simmered in dashi stock to add flavor.

📋 Ingredients

Here are the ingredients (amounts are in the recipe card below).

• Vegetables　>> Onion, carrot, potatoes, garlic
• Koyadofu　>> Use bite-size (1/6 size) koyadofu for this recipe. If it is a regular full-size, cut it into smaller pieces before use. (please see the next section)
• Soybeans　>> I prefer to cook dry soybeans in a pressure cooker (I usually cook them in bulk and store them in the freezer). Canned soybeans are also ok.
• Broth　>> I use vegetable broth powder, which doesn’t include any animal ingredients.
• Canned tomato　>> Canned diced tomatoes or whole tomatoes, both are ok.
• Salt and pepper

Size of Koyadofu

If you haven’t purchased koyadofu yet, here is some information for you.

Koyadofu is sold in different sizes like the picture. Full size is most common size and others are cut into smaller sizes. We use 1/6 size for this recipe.

I always stock full size, 1/6 size and thin slices. The 1/6 size is often used for simmered dish or when I just want to use a little bit. Full size is often used when koyadofu is the main ingredient, such as Koyadofu katsu(cutlet).

By the way, the thin slices does not require soaking in the water. You can put it in miso soup or stir-fry as it is, so it is very convenient because you can quickly use it when you do not have time for soaking.

If you are first time to cook koyadofu, the full size is good to start, and easy to find at an asian grocery store. Please cut into small pieces according to the recipe.

🔪Instructions

How to make is very simple! Let me show you the steps. You can also watch this video.

1. Cut ingredients：Chop garlic, and cut all the other vegetables into 1 cm cube.  Soak koyadofu in the water, drain, and cut into 1 cm cube also.
2. Fry the garlic：Add oil to a pan, and fry the garlic over low heat.
3. Stir fry vegetables：When you smell the garlic, stir fry the vegetables over medium heat in the order of onion → carrot → potato.
4. Add other ingredients：Add koyadofu, soybeans, salt, broth, canned tomato and water, and mix lightly
5. Simmer：Bring it to a boil, cover and simmer on low heat for 10 minutes until vegetables get tender
6. Adjust the taste：Open the lid,  confirm if the vegetables are cooked well, and add salt and pepper to adjust the taste.

Here you go! It is delicious both cold and warm. I like to eat it after it has cooled down and the taste has settled down.

The finished product is quite large portion(fills an 850 ml container). If you cannot eat it all soon, I would recommend to put it in a freezer bag and store in the freezer. It will last for a month.
