Sauce ravigote

Sauce ravigote is a classic, lightly acidic sauce in French cuisine, which may be prepared either warm or cold. The warm sauce is based upon velouté, cut with white wine vinegar, though not classically with Dijon mustard as it is universally nowadays, and the cold is a vinaigrette based on a meat glaze. Many other preparations pass under the term ravigote, but in general ravigote sauces are highly seasoned with chopped, sautéed shallots or onion, capers and herbs: ravigoté connotes "reinvigorated", "freshened up". It is generally served with mild flavored proteins or those that have been boiled or poached, such as fish, fowl, eggs and, traditionally, with tête de veau, jellied hare, head cheese, pâté or calves' brains.
