Sauce gribiche

Sauce gribiche is a cold egg sauce in French cuisine, made by emulsifying hard-boiled egg yolks and mustard with a neutral oil like canola or grapeseed. The sauce is finished with chopped pickled cucumbers, capers, parsley, chervil and tarragon. It also includes hard-boiled egg whites cut in a julienne.

Classically, sauce gribiche may be served with boiled chicken, fish (hot or cold), calf's head, tripe, or cold terrine. Modern variations pair sauce gribiche with vegetables, such as asparagus, charred lettuce or leeks, or served as a dip.
