Ingredients

2 cups apple-cider vinegar 

1/2 cup soy sauce 

1/4 cup light-brown sugar 

1 teaspoon ground ginger 

1 teaspoon ground yellow mustard seed or dry mustard 

1 teaspoon onion powder 

1 clove garlic, crushed 

1/2 teaspoon ground cinnamon 

1/2 teaspoon freshly ground black pepper 

Preparation

Place all ingredients in a medium saucepan. Bring to a boil over medium-high heat; reduce heat to a simmer and cook until liquid is reduced by half, about 20 minutes. Strain through a fine-mesh sieve and let cool completely before using. Worcestershire sauce may be stored in an airtight container, refrigerated, for up to 3 months.
