Mirin

Mirin is a sweet Japanese rice-based seasoning traditionally made by fermenting glutinous rice, rice koji and shochu or another distilled spirit. It contributes sweetness, gloss and depth to sauces and marinades. Traditional hon-mirin contains alcohol, while lower-cost mirin-style seasonings may have different ingredients and alcohol levels.

Types of mirin

• Hon-mirin: Traditional mirin made through fermentation and maturation. It generally contains alcohol and has a rounded sweetness and depth.
• Shio-mirin: A mirin style containing added salt, which may affect its classification and use as a seasoning.
• Mirin-style seasoning: Often called mirin-fu chomiryo, these products may use added sweeteners and other ingredients and can have lower or no alcohol. Check the product label.

How mirin is used in Japanese cooking

Mirin adds sweetness, aroma and a glossy finish to sauces and cooked foods. It is commonly used in teriyaki, tare, yakitori glaze, simmered dishes, marinades and noodle broths. It can help balance salty ingredients such as soy sauce and deepen the flavour of a sauce as it reduces.

Mirin versus sake

Mirin is generally sweeter and is used primarily as a seasoning. Sake is a brewed alcoholic beverage that can also be used in cooking, where it contributes aroma and flavour but is usually less sweet. Some recipes combine both mirin and sake to balance sweetness, acidity, aroma and alcohol.

How to substitute mirin

If mirin is unavailable, a recipe may use sake or another suitable liquid with a measured amount of sugar, but the result will not be identical. The best substitution depends on the dish and the product being replaced. Avoid substituting rice vinegar directly: vinegar is acidic, while mirin is primarily a sweet seasoning.

Label and product checks

Check the ingredient list, alcohol content, salt and sweetness before using a product. Different mirin-style seasonings vary significantly, so adjust the recipe rather than assuming that every bottle has the same concentration or flavour.

Example: Combine mirin with soy sauce, sake and sugar for a teriyaki-style glaze, or use it in a tare for yakitori.

Chef’s tip: Add mirin early enough for its flavour to integrate into a cooked sauce, but taste before adding extra sugar. A sweetened mirin-style product may already provide sufficient sweetness.

Key distinction: Hon-mirin is a traditional fermented rice seasoning, while mirin-style products may use added sweeteners and have different alcohol and salt levels. Mirin is not the same as rice vinegar.
