Boil 4 ozs. macaroni and drain. Butter a pie-dish and put in half the macaroni. Scald 4 or 5 tomatoes in boiling water for a few minutes, when the skin will come off easily. Boil 2 eggs hard and slice. Have 2 ozs. cheese grated, and sprinkle half of it over the macaroni, then put half of the eggs and half the tomatoes. Season with salt, pepper, and a little grated onion (I keep an old grater for the purpose). Take 8 or 10 medium-sized flap mushrooms, if to be had, clean and trim, removing the stalks. Add a layer of them, and repeat as before, but put the mushrooms before the tomatoes. Cover the top thickly with bread-crumbs. Make a stock with the trimmings of mushrooms and tomatoes. Put dessertspoonful butter in saucepan, stir in half teaspoon flour, same of made mustard, and perhaps a little ketchup. Add the stock--there should be about a teacupful--stir till it boils, and pour equally over the pie. Dot over with bits of butter, and bake one hour in fairly brisk oven. In case this pie may be voted rather elaborate by some, I may say that it is excellent with several of the items left out. The eggs, mushrooms, cheese--any one of these, or all three may be dispensed with, and what may be lost in richness and flavour will be compensated in delicacy and digestibility. Any of this pie that is left over may be made into cutlets, so that one can have a second dish with little extra trouble. NOTE.--When fresh tomatoes are not to be had tinned ones will do.
