Wonderful sauce! I cooked my tenderloins on the grill, but made this sauce on the stovetop by starting at step 10, adding the garlic, rosemary and thyme alond with the shallots. It was a perfect accompaniment to rare tenderloins, and 1/3 of the recipe was more than enough for two steaks. This is a definate make again!
