68. Eel Broth, very strengthening.—Take a small eel, which skin as described, and wash well, then cut into slices, which put into a small saucepan, just covered with water, add a little salt, a few sprigs of parsley, two button onions, and a clove; let it simmer very gently until the eels are tender, when skim off all the fat, pass the broth through a very fine sieve into a cup: it is then ready to serve when required, but a spoonful only should be taken at a time.
A patient is sometimes allowed to take part of the fish, which being so much boiled, constitutes a lighter food than eels are in general; a little melted butter and parsley might be served with them.
