Œufs aux topinambours should be prepared in this wise :—Choose a dozen good-sized Jerusalem artichokes, trim, boil, and set them to cool; take six hard-boiled eggs, let them get cold and cut them up; cut the artichokes into slices, set them in a buttered pie-dish; strew the chopped hard-boiled eggs over them, pour over the whole some thickly-worked volouté au Parmesan, and heat the mixture thoroughly in the oven. A dusting of hot rasped crust crumbs should be given on taking the dish from the oven.
