Worcestershire Sauce Overview

Worcestershire sauce is a fermented liquid condiment made from vinegar, anchovies, molasses, spices, and flavorings. While it contains small amounts of sugar, it is typically used in very small quantities, resulting in low net carbs per serving. It can fit low-carb and diabetic-friendly cooking when portion-controlled.
