Grilled Bison with Rosemary Butter

We ordered some grass fed Bison steaks from Tropical Traditions. Bison steaks are leaner than beef steaks and I learned that Bison should not be cooked past medium rare or there is a change in flavor.  These steaks were seasoned with Alfie's seasoning, grilled and left to rest for about 15 minutes, then topped with rosemary butter before serving.

4 Tablespoons butter, unsalted

Grilled Bison with Rosemary Butter

1 teaspoon fresh rosemary leaves, finely chopped
1 Tablespoon green onion, finely chopped
1 garlic clove, minced
1/2 teaspoon kosher salt
few grinds of fresh ground pepper

Mix all the ingredients together in a small bowl. On a small sheet of wax paper, spoon butter into the form of a log and roll wax paper around, twist end and refrigerate until ready to use.
Slice the chilled butter and top it on rested steak. Any remaining butter can be frozen for future use.
