A Cullis for Fish.
BROIL a jack or pike, till it is properly done, then take off the skin, and separate the flesh from the bones. Boil six eggs hard, and take out the yolks; blanch a few almonds, beat them to a paste in a mortar, and then add the yolks of the eggs: mix these well with butter, then put in the fish, and pound all together. Then take half a dozen onions, and cut them into slices, two parsnips, and three carrots. Set on a stew-pan, put into it a piece of butter to brown, and when it boils put in the roots; turn them till they are brown, and then pour in a little broth to moisten them. When it has boiled a few minutes, strain it into another saucepan, then put in a whole leek, some parsley, sweet basil, half a dozen cloves, some mushrooms and truffles, and a few crumbs of bread. When it has stewed gently a quarter of an hour, put in the fish, &c. from the mortar Let the whole stew some time longer, but be careful it does not boil. When sufficiently done strain it through a coarse sieve. This is a very proper sauce to thicken all made-dishes.
