354—Lucas Herrings

Raise the fillets from fine salted herrings, soak them first in cold water, and then in milk for an hour.

Prepare a sauce as follows:—Beat up the yolks of two eggs in a bowl with salt and pepper and one tablespoonful of mustard; add five tablespoonfuls of oil and two of vinegar, proceeding as in the case of mayonnaise, and complete with shallots and one dessertspoonful of chopped chervil and gherkins. Season with cayenne, immerse the drained and dried fillets of herrings in this sauce, and send them to the table on a hors-d’œuvre dish.
