You've probably used it to season Asian food, whether homemade or takeout, but you may still wonder, "What is soy sauce?"

It adds flavor to a bed of stir-fried rice noodles or can be used to marinate pork chops or flank steak for a main dish.

Soy sauce can be beneficial for gut health, but its high levels of histamines can also trigger allergies. Some substitutions may prevent unwanted reactions. Read on for more information about what soy sauce is made of, how to use it, and what sauces and flavorings you can substitute to avoid its high sodium content and allergens.

What Is Soy Sauce?

What Does Soy Sauce Taste Like?

Soy sauce provides a salty, savory flavor to dishes when used as a condiment. You might also find some varieties of soy sauce to provide a hint of sweetness, sourness, and/or bitterness.

How Is Soy Sauce Made?

Back in 17th century China, when this salty condiment got its start, soy sauce was traditionally made by soaking and cooking the soybeans in water before combining them with crushed wheat and a bacterial culture such as Aspergillus. The wheat could be roasted, or other ingredients could be added to provide more flavor. From there, it's aged and fermented—a process that can take days or months.

Today, there are ways the food production world speeds up the process without fermentation through chemical production by mixing the soybeans with hydrochloric acid, which breaks down the proteins in the soybeans. In this soy sauce-making variation, additional color and salt are usually added to achieve the desired flavor.

Types of Soy Sauce

Soy sauce varieties go beyond plain. Different types from different parts of Asia complement certain dishes. You can find hundreds of varieties in your local Asian market.

  • Light soy sauce: This is the variety you'll most commonly find in grocery stores and on the table at restaurants. You'll want to use it in recipes simply calling for "soy sauce" or to add flavor to dishes as a condiment.
  • Dark soy sauce: This variety of soy sauce is thicker and darker, resulting in a sweeter and richer flavor. Due to the sweetness, it may taste less salty than regular light soy sauce, but the sodium content is still about the same (or less). It is commonly used to make sauces for dishes such as beef and broccoli or to give fried rice a deeper flavor.
  • Low-sodium soy sauce: If you're following a low-sodium diet for health reasons, low-sodium soy sauce can be used interchangeably with regular soy sauce. The difference here is that sodium is removed from the sauce once brewed. As a comparison, 1 tablespoon of regular soy sauce will have approximately 900 mg of sodium vs. 550 mg of sodium.

Soy Sauce Substitutes and Gluten-Free Options

Since traditional soy sauce is made with wheat, you might be wondering how to enjoy that same flavor if you have allergy restrictions. Good news: There are plenty of gluten-free soy sauces and substitutes to complete your recipes. Feel free to use any of these in place of soy sauce for a gluten-free option:

  • Tamari: This is a Japanese soy sauce made solely from soybeans without any wheat. It's processed similarly and still provides the same salty, umami flavor as the wheat-included varieties.
  • Coconut aminos: This dark brown sauce looks like soy sauce but is made from the sap of a coconut plant (not the actual coconut) without any soy or wheat. It's fermented, and the natural sugars are released, revealing a liquid that tastes nothing like coconut but rather perfectly savory.
  • Liquid aminos: This dark-colored liquid can be made with hydrolyzed soybeans and/or coconut sap. If you have a soy allergy, make sure you're looking for ones without any soy.
  • Worcestershire Sauce: This fermented liquid condiment is made with a blend of vinegar, molasses, anchovies, garlic, tamarind, chili pepper, and salt. Used in more Western cuisine, it doesn't have the same flavor as soy sauce but will still provide a savory, umami flavor to your dishes.

Soy Sauce Storage

Like any product you find on grocery store shelves, soy sauce has an expiration date on the package. But does soy sauce go bad? Unopened bottles can be stored in the pantry for two to three years. Once opened, the microorganisms in soy sauce make it OK to keep the opened bottle in the pantry as well, but it may start losing its original flavor after six to seven months. It's recommended to keep opened bottles in the refrigerator to keep soy sauce tasting its best.
