Grill your beef sirloin to perfection with a miso marinade that will add subtle flavors of ginger, garlic, and chili pepper while drawing out the naturally balanced steak flavors.
Blend Miso, ginger, soy sauce, sake and garlic in a blender. Transfer into a pot and add all remaining ingredients except beef sirloin.
Bring to a boil, then immediately turn off heat. Set aside until mixture cools.
Spread half the mixture in a container. Lay 2 pieces of cheese cloth on top (to make a double layer of cloth). Place beef on cloth and lay 2 remaining cloths over beef. Spread remaining mixture on cloth.
Cover container with plastic wrap and marinate for 3 hours in refrigerator.
Grill marinated beef over charcoal or electric indoor grill.
Recipe Tip: The cheese cloth makes it very convenient for removing all excess marinade mixture from the meat. This prevents meat burning from the heat while cooking.
