Peel the vegetable marrow, cut it into even rings about three-quarters of an inch thick, and remove the seeds neatly (this is best done by the aid of a pastry cutter). Dissolve the butter in a baking tin, place the rings in, sprinkle a little salt on them, and bake in a hot oven for half an hour, then turn them over and bake another half hour. Meanwhile prepare the batter as follows: take half a pound of cooked tomato pulp, as dry as possible, and chop it well; add pepper and salt if not already seasoned. Make a batter with the egg, flour and milk, add the tomato pulp, and stir all well together. When the rings of marrow have been cooking one hour, remove from the oven, fill up the centres with the batter, replace in the oven, and bake another half hour.
Tomato sauce should be served with this dish, which can be specially recommended.
