Fermentation in Japanese cuisine
Fermentation is like natural alchemy. Under the action of micro-organisms such as lactic acid bacteria, yeast or the koji fungus (Aspergillus oryzae), food is transformed, developing new flavors and invaluable nutritional richness. There are several types of fermentation:
-
Lactic: perfect for Japanese pickles (tsukemono), which gain in acidity and crunchiness.
-
Alcoholic: essential for making sake and mirin, providing subtle, complex aromas.
-
By koji: the fungus behind miso, soy sauce and shōchū.
Japanese fermentation is nothing new! As far back as the Yayoi period (300 BC - 300 AD), it was already practiced to preserve food and enhance its flavors. Over the centuries, techniques were refined, becoming an essential pillar of Japanese gastronomy. Today, this age-old tradition continues to amaze gourmets the world over.
Japan's main fermented foods
Miso: Miso, a fermented paste made from soy, rice or barley, is a staple of Japanese cuisine. Its taste varies according to the length of fermentation, from mild white miso to more robust red miso. Rich in probiotics and nutrients, it is the basis of the famous miso soup and is also used to season many dishes.
Natto: Hated by some, adored by others, natto is a fermented soy-based food whose viscous texture and powerful aroma leave no one indifferent. Rich in vitamin K2 and probiotics, it is often eaten for breakfast with rice and soy sauce.
Tsukemono: Tsukemono are vegetables marinated in salt, rice bran or miso. These pickles accompany almost every Japanese meal, adding a touch of freshness and crunch that balances the flavors of the dishes.
Shoyu (soy sauce): This brown sauce made from fermented soybeans is an essential ingredient in Japanese cuisine. It is used for seasoning, marinating or as a base for soups and sauces. Its characteristic umami, slightly salty taste varies according to type (light or dark soy sauce).
Sake: Sake is an alcoholic beverage made by fermenting rice. Traditionally used in Shinto rituals, it is also a common accompaniment to meals. It comes in several varieties, from dry to sweet, and is often consumed hot or cold.
Amazake: A sweet, fermented rice-based drink, amazake is lightly alcoholic. Served lukewarm, it is most often consumed during the holidays or as a comforting snack. Its natural sweetness comes from the rice fermentation process.
Mirin: A mild sake used mainly in cooking, mirin adds a sweet, umami touch to dishes. It is indispensable in the preparation of sauces for sushi, teriyaki, or for deglazing vegetables. Its low alcohol content and sweet taste make it an excellent complement to savory sauces.
Kampyo: Imagine dried squash, rehydrated and transformed into a delicious garnish that adds a subtle, flavorful touch to your Japanese dishes. The kampyo is an essential ingredient in recipes such as makizushiwhere it adds a tender texture and mild flavor.
Kuzu: The kuzu is a starch extracted from the root of the kudzu plant, which gives dishes a smooth, creamy texture. Used mainly to thicken soups and sauces, it is a true secret of Japanese cuisine. When added to sauces such as teriyaki or broths kuzu creates a perfect consistency and an appetizing sheen.
Shio-koji: Visit shio-kojia mixture of salt, koji and water, is a true treasure of Japanese cuisine. This fermented seasoning is used to marinate meat, fish and vegetables, bringing incomparable depth of flavor. Thanks to its fermentation, it releases umami aromas that naturally enhance your dishes.
Fermented Food Manufacturing Process
At the heart of Japanese fermented products are a few simple but essential ingredients. Vegetables, soy, rice and koji are the key ingredients in this culinary alchemy. Koji transforms grain starches into fermentable sugars, a process that allows micro-organisms to work their magic and reveal deep, complex flavors.
Fermented food production in Japan is an ancient art, handed down through the ages. Using techniques such as slow maceration, delicate salting or the inoculation of rice or soybeans with koji, each step of the process is carefully executed. These ancestral methods allow flavors to develop slowly and naturally, transforming each ingredient into a treasure trove of taste and texture.
The micro-organisms (lactic acid bacteria, yeast, koji) are the true artisans of this transformation. They metabolize the ingredients, creating inimitable flavors and precious nutrients such as health-giving probiotics.
Fermentation doesn't just happen. It takes place under conditions, where temperature and humidity are meticulously controlled. A moderate temperature, combined with just the right humidity, enables the micro-organisms to work in the best possible conditions.
Fermentation techniques :
Slow maceration: An ancestral technique, slow maceration allows ingredients to develop rich, complex aromas. Immersed in salt, vinegar or miso, they ferment over several weeks, creating deep flavors and melting textures, ideal for tsukemono and miso.
Salting: Unlike raw salting, this method uses a precise amount of salt, sometimes combined with koji, for balanced fermentation. It preserves texture and enriches flavors, giving rise to umami condiments like shio-koji.
Inoculation: The key to Japanese fermentation, inoculation involves introducing koji into rice, soy or barley. This fungus transforms the ingredients by releasing sugars and amino acids, revealing the umami of miso, shoyu and sake.
Local traditions play a fundamental role in the manufacture of fermented foods. These recipes, shaped by centuries of history and influenced by the local climate and resources, offer an astonishing palette of flavors.
