EGGPLANT À LA CRÉOLE

Peel a young eggplant, cut it into dice, and simmer for ten or fifteen minutes in half a cupful of boiling water. Drain and press out the liquid. Chop fine two onions, fry in butter, add the eggplant, salt and pepper to season, and one tablespoonful each of minced parsley and vinegar. Add also two heaping tablespoonfuls of butter. Put into a baking-dish, cover with crumbs, dot with butter, and bake for twenty-five minutes.
