Worcestershire sauce is a blend of many ingredients that add a savory quality to recipes, sauces and marinades. The sauce usually contains anchovies, onions, garlic, water, vinegar, molasses, salt, sugar, tamarind, cloves and chili peppers. Worcestershire sauce may need to be replaced in a recipe due to dietary restrictions, including veganism or a low-sodium diet, or if you've simply run out of the sauce and need a quick substitute. The best alternative is to make your own.
Feel free to leave out any individual ingredients when making homemade sauce. For example, if you're not a fan of garlic, leave it out; it doesn't necessarily have to be replaced in order to make a delicious sauce. You can create a vegan sauce by holding the anchovies. Here's Martha Stewart's recipe.
Mix ingredients together in a saucepan and bring to a boil. Let simmer and reduce for 20 minutes. Strain and cool before using in recipes or sauces.
You may also replace 1 teaspoon Worcestershire sauce with 1 tablespoon soy sauce, a dash of sugar, 4 drops of hot sauce, and 1/8 teaspoon of lemon juice.
Steak sauce such as A1 works to replace Worcestershire. Sub it in at a 1:1 ratio.
