Ingredients

1/2 cup Worcestershire sauce
1/2 cup soy sauce
3 drops liquid smoke (I prefer the Mesquite flavor, but use it sparingly, as too much will cause a bitter taste.)
3-5 drops sesame oil
garlic (I use 2 tablespoons)
cracked black pepper (Lots of it!)
yellow mustard (enough to make it a nice light brown color)

Directions

Pour over burgers or steaks and let sit in refrigerator for 1 hour. (Roughly the time it takes to watch that Sopranos episode you missed on HBO On Demand) You can even mix a little into the burger while forming patties.Cook over hardwood charcoal fire. Grill should be hot enough to sear outside quickly.
