Combine the ketchup, water, white vinegar, Worcestershire sauce, and soy sauce over medium heat in a saucepan.
Stir well to combine the ingredients, and let the mixture come to a gentle simmer.
Adding Flavor:
Add the minced garlic, finely chopped onion, light brown sugar, black pepper, and cayenne pepper to the simmering sauce.
Continue to stir the mixture, thoroughly combining all the ingredients.
Simmer And Reduce:
Reduce the heat to low and allow the sauce to simmer for approximately 20-25 minutes. This will give the flavors time to meld and the sauce to thicken to your desired consistency.
To keep the sauce from sticking to the pan’s bottom, stir from time to time.
Cool And Store:
Once the sauce has reached your preferred thickness, remove it from heat and let it cool to room temperature.
Transfer the Peter Luger Steak Sauce into a glass jar or an airtight container for storage. It keeps for up to one month in the refrigerator.
Serve And Enjoy:
Your homemade Peter Luger Steak Sauce is ready to elevate your steak experience. Drizzle it generously over your favorite grilled or pan-seared steak cuts, and savor the incredible flavors.
