White Onion Sauce.—(No. 298.)
The following is a more mild and delicate240-* preparation: Take half a dozen of the largest and whitest onions (the Spanish are the mildest, but these can only be had from August to December); peel them and cut them in half, and lay them in a pan of spring-water for a quarter of an hour, and then boil for a quarter of an hour; and then, if you wish them to taste very mild, pour off that water, and cover them with fresh boiling water, and let them boil till they are tender, which will sometimes take three-quarters of an hour longer;[241] drain them well on a hair-sieve; lay them on the chopping-board, and chop and bruise them; put them into a clean saucepan, with some butter and flour, half a tea-spoonful of salt, and some cream, or good milk; stir it till it boils; then rub the whole through a tamis, or sieve, adding cream or milk, to make it the consistence you wish.
Obs.—This is the usual sauce for boiled rabbits, mutton, or tripe. There must be plenty of it; the usual expression signifies as much, for we say, smother them with it.
