• Combine all ingredients in a large Pyrex measuring cup or mixing bowl and whisk together.
• Place steak in a large, ziploc bag and pour marinade over the top. Close securely.
• Marinate for at least 4 hours and up to 24 hours. (A bare minimum of an hour.)

To grill

• Preheat grill to medium high heat and lightly oil the grates.
• Remove the steak from the marinade and pat dry to remove excess marinade and to prevent flare-ups on the grill.
• Grill steak to desired doneness.
• Remove steaks from grill and tent with foil. Let rest for at least 5 minutes before serving.

For the Garlic Herb Butter

• Cream softened butter with a spoon or mixer just until smooth. Stir in garlic and chopped herbs until combined.
• Spoon butter mixture onto a square or parchment paper, plastic wrap or wax paper and shape into a log (about 6 inches long). Pull the paper or plastic wrap tightly around it and roll up, twisting the ends tightly.
• Chill in the refrigerator until the butter is solid again, about 2 to 3 hours. Slice and serve on bread, steak, potatoes, shrimp whatever you want!
