The name mignonette originally refereed to a bundles of peppercorns, cloves , and spices. Now it usually means just peppercorns. This is a mix of equal parts black and white peppercorns.
You can use this as a rub on large cuts of beef, chicken or lamb. As a rub we recommend using 1 tsp per pound of meat. This also adds delicious flavour to any thing you add black pepper to.
