In vegetarian cooking, there are many tricks to add depth of flavor to your dishes. Among the most appreciated ingredients, miso and tamari are prominent when it comes to intensifying the famous taste known as umami. If you are already familiar with Japanese cuisine, you may know them; if not, get ready to discover two key products to enhance your dishes and give them an irresistible character.

What is umami?

You have surely heard of the four basic tastes: sweet, salty, sour, and bitter. But did you know that, technically, there is a fifth? It is umami, a term of Japanese origin literally meaning “delicious” or “savory.” Umami is detected thanks to the presence of glutamate and ribonucleotides (such as inosinate or guanylate) in our foods.

This taste is notably found in fermented products or those rich in proteins and amino acids. Sauces, broths, aged cheeses, and mushrooms like shiitakes are particularly rich in umami. In vegetarian cooking, replicating the rich flavor that some attribute mainly to animal products can sometimes be complex. This is where miso and tamari come in. These two products, primarily derived from the fermentation of soybeans, bring a depth and complexity that will delight your taste buds.

Understanding miso

Miso is a fermented paste mainly composed of soybeans, salt, and koji (a fungus used for fermentation). There are different varieties of miso, each with its own character and flavor palette:

• Shiro miso (white miso): the mildest and least salty. It is usually made with white rice and a lower proportion of soybeans. This variety is ideal for those new to miso, as its subtle and slightly sweet taste is well-suited to light sauces, delicate soups, and dressings.
• Aka miso (red miso): more robust. It is fermented longer and often made with soybeans and barley or sometimes more complete rice. Its powerful and salty flavor makes it an ideal ally for enhancing rich dishes like thick soups, tofu marinades, or even some roasted vegetable preparations.
• Brown or barley miso (mugi miso): fermented with barley and soybeans. It can have a darker color, tending towards brown. Its aromas are more complex, sometimes earthy, and it is particularly interesting for robust sauces and stews.
• Dashi miso: supplemented with dashi (a traditional Japanese broth). In vegetarian cooking, ensure the dashi is made from shiitake mushrooms or kombu seaweed, rather than dried bonito. This type of miso is convenient for making very flavorful broths in no time.

The benefits of miso

Miso is renowned for its nutritional benefits, especially when unpasteurized. It contains lactic bacteria and enzymes beneficial to our intestinal health. The beneficial bacteria can help improve digestion and support the immune system. Miso is also a source of protein, B vitamins, and minerals (particularly zinc and manganese).

However, be mindful of the salt content: miso is often salty, so it is best to taste before adding more salt to your preparations. Additionally, if you want to retain the probiotic benefits of miso, avoid cooking it too long at high temperatures. Add it towards the end of cooking.

Different uses of miso

1. Soups: Who doesn’t know the famous miso soup? In traditional Japanese cuisine, a bit of miso is dissolved in a dashi broth before serving it with green onions, tofu, and sometimes wakame seaweed. In a vegetarian version, use a broth made from kombu and shiitake mushrooms. If you serve it at the end of a meal (as is customary in Japan), it provides a comforting note and aids digestion.
2. Marinades: Miso can serve as a base for marinades for tofu, tempeh, or vegetables. Mix it with a bit of lemon juice, sugar, garlic, ginger, and a touch of vegetable oil. Let marinate for several hours, or even overnight, for a deep result.
3. Dressings: A teaspoon of miso can transform a simple dressing into a sauce with umami accents. Mix it with rice vinegar, sesame oil, a hint of maple syrup, and a bit of water to adjust the consistency.
4. Sauces and condiments: Miso is an excellent starting point for creating creamy sauces, perfect for accompanying pasta, grains, or steamed vegetables. You can add soaked cashews, nutritional yeast, or even a bit of mustard to further enhance the flavor.

Understanding tamari

Tamari is a type of soy sauce born from the miso fermentation process. Unlike classic soy sauce (shoyu), tamari generally contains little or no wheat, making it a more suitable option for those sensitive to gluten (be sure to check the label). Made from the fermentation of soybeans, water, and salt, it is distinguished by a rounder, deeper taste and often less sweet than standard soy sauce.

The benefits of tamari

Like miso, tamari is naturally rich in compounds that contribute to umami. Additionally, it contains essential amino acids from soybeans. Compared to ordinary soy sauce, tamari often has a slightly superior nutritional profile in terms of protein, although this remains moderate for a sauce. Its main asset lies in its taste qualities and its low or absent gluten content.

Different uses of tamari

1. Table condiment: You can use tamari instead of salt in many dishes. Its richer flavor profile than a simple pinch of salt will add depth, especially on a bowl of rice, steamed vegetables, or a grain mix.
2. Marinades and sauces: Tamari blends perfectly with various spices (ginger, garlic, chili…) or sweet elements (honey, maple syrup, fruit juice). It works particularly well in marinades for tofu, seitan, or mushrooms.
3. Seasoning soups and broths: Adding a dash of tamari to a potage or vegetable soup can instantly enhance the flavor. However, be careful to add it sparingly, as it is concentrated.
4. Cold preparations: Tamari incorporates very well into salad dressings, dips, or even raw sauces made from almond butter, cashew nuts, or tahini.

Miso vs Tamari: what are the differences?

Although these two products come from the fermentation of soybeans, their use and taste differ:

• Texture: Miso is a dense paste, while tamari is a liquid.
• Fermentation properties: Miso, especially if unpasteurized, can retain active enzymes and probiotics. Tamari, often pasteurized, does not necessarily offer the same benefits.
• Flavor profile: Miso, with its sweet, tangy, or robust nuances, can sometimes resemble cheese or a fermented food. Tamari is a salty condiment, more linear but very concentrated in umami, with a slightly sweet and very powerful taste.
• Use: Miso is well-suited for soups, thick sauces, creamy marinades, while tamari is more like a liquid sauce, a bit like a “liquid salt” enhanced.

The virtues of fermentation

Miso and tamari share a major common point: fermentation. This process, found in many foods (sauerkraut, kimchi, kombucha…), allows the development of complex flavors and transforms foods into nutritional powerhouses. The microorganisms responsible for fermentation (like koji for miso) partially predigest proteins and carbohydrates, which can facilitate assimilation by the body and magnify aromas.

Why is fermentation beneficial?

1. Improved digestibility: Fermented soy proteins can be easier to digest than non-fermented soy.
2. Nutrient enrichment: Often, fermentation increases the bioavailability of certain vitamins and minerals.
3. Probiotic interest: When miso is unpasteurized, it provides probiotic strains that support intestinal flora and thus the immune system.

Tips for choosing and storing miso and tamari

The Japanese food market has expanded, and there is now a wide variety of misos and tamari sauces available in Asian grocery stores, organic shops, or some regular supermarkets. A few key points:

• Read the label: Check the ingredient list and see if the product is pasteurized or not. If you are looking for the probiotic effect, prefer the “unpasteurized” mention. For tamari, if you are gluten intolerant, make sure it is 100% wheat-free.
• Color is no coincidence: A lighter miso is often milder and sweeter, while a darker miso will be stronger. Choose based on how you plan to use it.
• Storage: Miso should be kept in the refrigerator, especially if unpasteurized, and can be stored for several months (or even a year) after opening. Tamari should also be kept cool after opening to best preserve its quality.

How to incorporate miso and tamari into everyday cooking

For amateur or seasoned cooks, miso and tamari can quickly become valuable assets in the kitchen. Here are some ideas to adopt them daily:

1. In improvised soups

When you don’t have time to cook a complex dish, quickly concoct a soup with seasonal vegetables. Add a bit of miso at the end of cooking to enhance the flavor and serve it with a dash of tamari if necessary. You’ll get a comforting soup, both light and rich in taste, without much effort.

2. On roasted vegetables

Roasted vegetables (carrots, squash, onions, beets…) are already very flavorful. To give them an even more gourmet twist, mix a bit of brown (or red) miso with olive oil, pepper, and brush your vegetables before baking. The result will be slightly caramelized and full of umami. After cooking, you can add a dash of tamari if you find the dish lacks salt or to accentuate the depth of flavor.

3. In your pasta dishes

This uncommon tip deserves to be known: make a “miso carbonara” or “miso cream” sauce by mixing in a saucepan a bit of white miso, plant-based cream (soy or oat), a bit of garlic, nutritional yeast, and pepper. Heat everything gently (without boiling for too long to avoid “killing” the miso enzymes if you care) and incorporate into your fresh pasta. You’ll be surprised by the creamy and savory result.

4. Marinades for tofu, seitan, and tempeh

Mix tamari with a hint of miso, grated ginger, lemon juice, and a natural sweetener (honey, maple syrup…) for a perfectly balanced marinade. Let the tofu or seitan marinate for at least 30 minutes, then cook in the oven or pan. You’ll get crispy pieces on the outside and soft on the inside, both enhanced with an irresistible umami fragrance.

5. In snacks and appetizers

For an original appetizer, prepare vegetable sticks (carrots, cucumber, bell pepper) with a sauce made from white miso, sesame paste (tahini), and a dash of tamari. The creamy consistency and slightly sweet-salty taste will please your guests. You can also offer edamame (green soybeans) steamed and garnished with a dash of tamari.

Tips for successful cooking and tasting

1. Taste before adding salt: Since miso and tamari are salty, it’s important to taste the preparation before adding salt, to avoid oversalting your dish.
2. Add at the end of cooking: If you want to retain the probiotic benefits of unpasteurized miso, add it at the very end of cooking and avoid prolonged boiling.
3. Store away from light: Even though the refrigerator is the ideal storage place, make sure to close containers tightly to avoid oxidation and the development of unpleasant odors.

Focus on environmental impact

As a vegetarian, it is interesting to consider the environmental impact of our food choices. Soy, in particular, is the subject of debate, especially due to deforestation linked to its cultivation in some parts of the world. To limit this impact, prefer:

• Organic products: Organic and responsible practices reduce pesticide use and often have a lesser impact on biodiversity.
• Committed brands: Learn about the origin of soybeans and the environmental policies of the brands you buy. Some ancient Japanese companies practice fair trade and use artisanal and less polluting production methods.
• Local or regional manufacturers: There are now miso and tamari producers in Europe or elsewhere, working in short circuits and sustainable agriculture. Keep an eye on these alternatives to reduce the carbon footprint related to the transport of raw materials.
