Boil four eggs a quarter of an hour. Dip them into cold water to prevent their looking blue. Peel off the shell. Chop the yolks of all, and the whites of two, and stir them into melted butter. Serve this sauce with boiled poultry or fish.
Put some grated crumbs of stale bread into a sauce-pan, and pour over them some of the liquor in which poultry or fresh meat has been boiled. Add some plums or dried currants that have been picked and washed. Having simmered them till the bread is quite soft, and the currants well plumped, add melted butter or cream.
This sauce is for a roast pig.
Take a large bunch of young green mint; if old the taste will be unpleasant. Wash it very clean. Pick all the leaves from the stalks. Chop the leaves very fine, and mix them with cold vinegar, and a large proportion of powdered sugar. There must be merely sufficient vinegar to moisten the mint well, but by no means enough to make the sauce liquid.
It is only eaten in the spring with roast lamb. Send it to table in a sauce-tureen.
