Tamari Sauce
Tamari is a Japanese sauce made from fermented soybeans, originally the liquid byproduct of miso production. Unlike most soy sauce, traditional tamari contains little to no wheat, giving it a darker color, thicker consistency, and a rounder, less sharp flavor with lower acidity.
Varieties
Not all tamari is wheat-free; some Japanese producers add a small percentage of wheat to the mash, so it isn't automatically interchangeable with certified gluten-free soy sauce. White tamari (shiro tamari) is a lighter, sweeter variant made with more wheat and less soy, closer in color to a light soy sauce.
Buying tips
Check the ingredient label carefully: some commercial tamari brands still include small amounts of wheat, so look for one labeled 'gluten-free' if that matters. Darker, thicker tamari with a short ingredient list (soybeans, salt, water, sometimes koji) tends to have a more complex, less one-dimensional flavor than thin, mass-produced versions.
Substitutes
Soy sauce (regular or low-sodium) — 1:1
The closest match in flavor and function, though it contains wheat and tastes slightly sharper and thinner.
Coconut aminos — 1:1, adjust salt
Naturally gluten-free and noticeably sweeter with about 40% less sodium; add a pinch of salt if using in a savory braise.
Liquid aminos — 1:1
Made from soybeans without fermentation; saltier and sharper than tamari but works fine in marinades and stir-fries.
Miso paste thinned with water — 1 tbsp miso whisked with 2 tbsp water replaces 3 tbsp tamari
Adds a similar umami depth but a grainier texture; strain if using in a clear sauce or dressing.
Fish sauce diluted with water — 1 part fish sauce to 1 part water replaces tamari 1:1
Only for savory cooked dishes, not raw dipping sauces; the fish flavor is noticeable but fades once heated.
Storage
Keep unopened tamari in a cool, dark pantry for up to two years. Once opened, refrigerate and use within 6 months for best flavor, though it won't spoil quickly due to its salt content.
How to use
Use as a 1:1 gluten-free swap for soy sauce in stir-fries, marinades, glazes, and dipping sauces for sushi or dumplings. Its lower acidity and rounder flavor also make it good stirred into soups and braises near the end of cooking rather than boiled hard, which mutes its aroma.
What it pairs with
Pairs well with rice vinegar and sesame oil in dipping sauces, with ginger and garlic in marinades, and with mirin in glazes for salmon or eggplant.
Nutrition
Tamari is high in sodium, typically around 900-1000mg per tablespoon, and contains small amounts of protein from the fermented soybeans. Because it's usually wheat-free, it's a common gluten-free pantry staple, though always check the label since some brands blend in wheat.
FAQ
Is tamari the same as soy sauce?
They're related but not identical. Soy sauce is traditionally brewed with a significant proportion of wheat, while tamari originated as the liquid drained off miso and traditionally contains little or no wheat, giving it a darker color and smoother, less sharp taste.
Is tamari always gluten-free?
Not automatically. Most tamari is wheat-free, but some brands add a small amount of wheat to the fermentation mash, so check the label if you need it to be strictly gluten-free.
Can tamari replace soy sauce in any recipe?
Yes, in a straight 1:1 swap for cooking purposes. The main difference cooks notice is a slightly milder, rounder flavor and a thicker texture, which can make sauces look a touch darker.
Why is tamari more expensive than soy sauce?
Tamari typically uses a higher proportion of soybeans and a longer fermentation process, and is produced in smaller batches by fewer manufacturers, which raises the cost compared to mass-produced soy sauce.
