DIY: How to Make Miso Paste at Home

Miso paste is a traditional Japanese seasoning that is used in many dishes. It is made by fermenting soybeans or other grains with salt and a type of fungus called koji. Miso paste is a great source of protein and is also packed with vitamins and minerals, making it a healthy addition to any meal. Making miso paste at home is easy and can be tailored to your taste preferences. Here’s how to get started.

First, you will need a few ingredients: soybeans, koji, and sea salt. You can find koji at Asian supermarkets or online. Begin by cooking the soybeans until they are soft and then mash them with a fork or blender until they are smooth. Combine the koji and sea salt with the mashed soybeans and mix thoroughly. Place the mixture in a jar or other sealed container and let it ferment at room temperature for a few days. The longer you let it ferment, the darker and more flavorful the miso paste will be. You can taste it along the way until it reaches the desired flavor. Once ready, the miso paste can be refrigerated and used in a variety of recipes.

Making your own miso paste at home is a great way to elevate your cooking skills. Not to mention, it’s a delicious and healthy addition to your diet. In this article, we’ll guide you through the process of making miso paste from scratch, step-by-step.

Ingredients Needed to Make Miso Paste

Before we dive in, here are the ingredients you’ll need to make miso paste:

1. Soybeans
2. Rice Koji or Barley Koji
3. Sea Salt
4. Distilled Water

Step 1: Soaking Soybeans

The first step is to soak the soybeans in water overnight. This helps to soften them, making it easier to cook and blend them later.

Step 2: Cooking Soybeans

After the soybeans have soaked overnight, it’s time to cook them. Drain the water and add fresh water to a stockpot or pressure cooker. Bring it to a boil, and then simmer the beans for about 3 hours for soft cooking, or 4 hours for a tougher texture.

Step 3: Mashing Soybeans

Once the soybeans are cooked, strain them and reserve the cooking liquid. Mash the beans using a food processor or a mortar and pestle.

Step 4: Mixing Soybeans and Koji

Next, it’s time to mix the mashed soybeans with the koji. The ratio should be 3 parts cooked soybeans to 1 part Koji.

Step 5: Adding Salt

Add salt to the mixture, about 6% of the total weight of the soybeans and koji mixture. This helps to create an environment that is hospitable for fermentation and prevents the growth of unwanted bacteria.

Step 6: Adding Water

After adding salt, add the cooking liquid that was reserved from cooking the soybeans earlier. If necessary, add distilled water to ensure that the mixture is loose enough for fermentation.

Step 7: Mixing the Mixture

Mix the miso paste mixture thoroughly to ensure that the salt and koji are evenly distributed throughout the mixture.

Step 8: Packing the Mixture in Jars

After mixing, pack the miso paste mixture into airtight glass jars.

Step 9: Fermenting the Miso Paste

Ferment the miso paste for at least 3 months to allow the koji to break down the complex starches in the soybeans into simpler sugars and amino acids.

Step 10: Enjoying Your Homemade Miso Paste

When the miso paste is ready, it will have a rich flavor and aroma. Use it to add depth to your soups, marinades, dressings, and more. Store the remaining miso paste in the fridge for up to a year.

With this guide, you can make your own miso paste and enjoy its delicious, umami flavor. Fermentation is an art, so don’t be discouraged if your first batch doesn’t come out perfect. Practice makes perfect and, over time, you’ll be able to tailor your miso paste to your exact liking.

Ingredients for Making Miso Paste

Now that you understand what miso paste is and its benefits, it’s time to start making your own. You can either buy the ingredients separately or buy a miso-making kit. Here are the ingredients you’ll need:

1. Soybeans: The primary ingredient for making miso paste is soybeans. Make sure to buy organic, non-GMO soybeans, as they are the healthiest option and won’t contain harmful chemicals.

2. Koji: Koji is a fermenting starter culture made from Aspergillus oryzae mold. It’s what converts the soybeans’ starch into sugar during the fermentation process, so it’s a crucial ingredient.

3. Salt: Salt helps to control the fermentation, slow down the growth of unwanted bacteria, and preserve the miso paste.

4. Water: You’ll need water to soak the soybeans and to make the miso paste.

5. Optional: You can add other ingredients to your miso paste, such as rice, barley, or other grains, to create different flavors.

The Process of Making Miso Paste

Here is the step-by-step process for making miso paste:

1. Soak the soybeans: Soak 3 cups of soybeans in 8 cups of water for at least 12 hours, or until the soybeans are soft.

2. Cook the soybeans: Drain the soaked soybeans and cook them in a large pot with fresh water for 3-4 hours, or until they are soft enough to mash easily.

3. Cool the soybeans: Once the soybeans are cooked, let them cool down to room temperature.

4. Mix the koji: In a separate bowl, mix 2 cups of koji with 1/2 cup of warm water until it reaches a smooth and thick consistency.

5. Mash the soybeans: Mash the soybeans until they are a smooth consistency.

6. Add salt: Add 1 1/2 cups of salt to the mashed soybeans and mix well.

7. Combine the soybeans, koji, and salt: Add the koji mixture to the salted soybeans and mix well.

8. Ferment the miso paste: Place the miso paste into a sterilized glass jar and press it down firmly to remove any air pockets. Cover with a lid and let it ferment in a cool and dark place for at least 6 months, or up to 2 years for a richer flavor.

9. Check on the miso paste: Check on the miso paste every few weeks, stirring it and pressing it down to remove any air pockets.

10. Store the miso paste: Once the miso paste has fermented, store it in the fridge, where it will keep for up to 1 year.

Now that you know how to make miso paste, you can enjoy its many health benefits and delicious flavor. Experiment with different ingredients to create your own unique miso paste recipe, perfect for adding to soups, marinades, dressings, and more.

Choosing the right ingredients

Making your own miso paste means having control over the quality of each and every ingredient that goes into it. Here are some tips on how to ensure that your miso paste is of the highest quality:

Soybeans

When making miso paste, it is important to use high-quality, fresh soybeans that are free from cracks and discoloration. Using old or stale soybeans can result in a miso paste that tastes off. It is also important to look for organic and non-GMO soybeans to ensure that your miso paste is as healthy and wholesome as possible.

Before starting, rinse your soybeans and soak them in water for around 12 hours. Soaking the soybeans will help to soften them, making it easier to blend them into a smooth paste.

Koji Rice

Koji rice is a specially grown rice that is essential to making miso paste. The koji rice is used to inoculate the soybeans and start the fermentation process. It is important to choose high-quality koji rice that is specifically meant for making miso paste. This rice can be sourced online or at specialty stores.

You will need to prepare the koji rice before starting the fermentation process. This involves steaming the rice and then inoculating it with koji spores to allow it to grow and develop the desired flavor and texture. This process can take anywhere from 24 to 48 hours depending on the temperature and humidity.

Sea Salt

The salt you use in your miso paste will have a significant impact on the taste and quality of the final product. It is important to choose unrefined, high-quality sea salt that is free from additives and impurities.

When adding the salt to your miso paste, be sure to use the correct ratio to ensure that the fermentation process is successful. Typically, for every cup of soybeans and koji rice combined, you will add one cup of sea salt.

Water

Water is added to the soybean-koji mixture to help create the ideal environment for fermentation to take place. It is important to use filtered or purified water to minimize the presence of impurities and chlorine. The amount of water that you add to your miso paste will depend on the desired consistency and flavor.

Once you have gathered all of your ingredients, it’s time to start the fermentation process. With the right ingredients and a bit of patience, you can make your own delicious and healthy miso paste right at home!
