It shows off best when added only at the very end. Scatter a few whole peppercorns over a steak, a beef tenderloin or pan-fried fish, press them in lightly and you're done. It works just as well in a pepper sauce, in butter for potatoes, over scrambled eggs, in pasta with oil and Parmesan, or with cream cheese or goat cheese on bread. It is also excellent in marinades and in a quick stir-fry of beef and garlic.
Since the peppercorns are already salted, only add more salt to the dish afterward. If you like it milder, rinse them briefly with water. After opening, store cool and tightly closed.
