Notes
Tips and Variations
Some brands of ketchup and Worcestershire sauce are sweeter than others. Taste the sauce as you stir it together, and adjust the amount of brown sugar to find the right level of sweetness.
Feel free to add fresh ginger, garlic cloves, or star anise to the sauce to build on the vibrant, aromatic flavors.
To make vegan katsu sauce, use vegan Worcestershire sauce (regular Worcestershire sauce contains anchovies).
If you can handle the heat, add 1 to 2 teaspoons of spicy sriracha sauce!
