Steak with Green Peppercorn Sauce

2 eight ounce flank steaks
1/2 teaspoon black peppercorns
1/2 teaspoon white peppercorns
2 tablespoons butter
1 clove garlic, crushed
1/2 cup beef stock
1 tablespoon peppercorns
2 tablespoons heavy cream
salt

1. Lightly press steaks into a mixture of black and white peppercorns and sprinkle with a bit of coarse salt.
2. Melt butter in a large skillet over medium heat. When it begins to foam, add the garlic, stirring around the pan, then sear all sides of the steaks.
3. Pour in beef stock and reduce heat to a simmer. Cover and cook until steaks are very tender, about 30-45 minutes.
4. Transfer the steaks to a warm place, add the green peppercorns to the skillet and bring the remaining liquid to a boil. Reduce until thick enough to coat a spoon.
5. Remove the skillet from the heat, allow to cool slightly, then slowly whisk in the heavy cream. Adjust seasoning as necessary and serve over steaks.
