No. 215 Turbot au gratin à la Provençale.
This dish is made from fish left from a previous dinner; pot two tablespoonfuls of chopped onions, and two of chopped mushrooms into a stewpan with two tablespoonfuls of salad oil; place it over a moderate fire five minutes, stirring it with a wooden spoon; then add three pints of brown sauce (No. 1), and reduce it one third, then add a clove of scraped garlic, a teaspoonful of Harvey sauce, one of essence of anchovy, a little sugar, a little cayenne, and two yolks of eggs, pour a little sauce on the dish you serve it on, then a layer of fish lightly seasoned with pepper and salt, then more sauce and fish again, finishing with sauce, sprinkle bread crumbs over it and place it in a moderate oven half an hour, or till it is very hot through, brown it lightly with the salamander and serve very hot. The garlic may be omitted if objected to, but it would lose the flavour from which it is named.
