An Onion Piqué is a French flavor booster used by chefs in stocks, soups, and sauces. It sounds fancy, but it only takes 3 ingredients (onion, cloves, and a bay leaf) and 10 seconds to make.
Trim off the root end of half a peeled onion. Attach a bay leaf to the cut-side of the onion using 2 or 3 whole dried cloves as "pins."
Add to a pot of stock or milk to cook and simmer as directed in your recipe. Remove and discard.
Notes
Onion: Peeled and cut in half through the root so the layers stay intact.
Cloves: Use 2 to 3 cloves for a half onion, or up to 6 for a whole onion, unless the recipe calls for a specific amount. They have a strong flavor, so use them judiciously.
