Soy sauce can be a secret ingredient in many recipes, even other than Asian food.
Here are some ideas for what other purposes soy sauce can be used for:
To flavor meat
Soy sauce contains a lot of glutamate, which acts as a natural flavor enhancer and makes meat tastier. Ground meat, roasts, meatballs, beef steamed in red wine or smoked, spicy grilled meat gains full flavor if you add some soy sauce. It can also be used in marinades, as soy sauce contains enzymes that break down the proteins. You can make sweet, spicy or hot marinades using soy sauce.
To add to sauces
Soy sauce blends well with a wide range of sauces, and it can also be added to intensely flavored soups such as goulash. If you make instant soup, you can enhance the taste by adding a spoonful of soy sauce, and vegetable soups and beef soup will become more flavorful too.
It adds a meaty flavor to vegan and vegetarian dishes
Because of the glutamate content of soy sauce it can be used in a vegan or a vegetarian diet to enhance a purely vegetable dish with a meaty flavor. It goes perfectly with spinach and mushrooms.
To add to cocktails
No one claims that soy sauce would be a panacea against hangover. However, it perfectly compliments cocktails that require a spicy flavor, such as bloody mary.
To add to canned sauces
When buying a ready-made sauce, you can enhance its flavor with 1-2 tablespoons of soy sauce. It makes flavors more balanced, reduces overly sweet tastes, and adds a spicy flavor.
