Dutch Apple Pudding

One pint of flour, one teaspoonful of cream of tartar, half a teaspoonful of soda, half a teaspoonful of salt, an egg, a generous two-thirds of a cupful of milk, two table-spoonfuls of butter, four large apples. Mix the salt, soda and cream of tartar with the flour, and rub through the sieve. Beat the egg light, and add the milk. Rub the butter into the flour. Pour the milk and egg on this, and mix quickly and thoroughly. Spread the dough about half an inch deep on a buttered baking pan. Have the apples pared, cored and cut into eighths. Stick these pieces in rows into the dough. Sprinkle with two tablespoonfuls of sugar. Bake in a quick oven for about twenty-five minutes. This pudding is to be eaten with sugar and cream or a simple sauce.
