Mignonette sauce
Condiment served with oysters
From Wikipedia, the free encyclopedia
Mignonette sauce is a condiment made with minced shallots, cracked pepper, and vinegar traditionally served with raw oysters.

The sauce originated in France. The French term mignonnette originally referred to a sachet of peppercorns, cloves, and spices used to flavor liquids, but now means cracked pepper.
While mignonette sauces may differ based on the type of vinegar, all contain pepper and shallots.[1][2][3] Common vinegars used to make the sauce include champagne, red wine, or white wine vinegar.[4]
