You can convert them into what are called Hard Rusks, or Tops and Bottoms, by splitting them in half, and putting them again into the oven to harden and crisp.
MILK BISCUIT.—
Cut up three quarters of a pound of butter in a quart of milk, and set it near the fire to warm, till the butter becomes soft; then with a knife, mix it thoroughly with the milk, and set it away to cool. Afterwards stir in two wine glasses of strong fresh yeast, and add by degrees as much sifted flour as will make a dough just stiff enough to roll out. As soon as it is mixed, roll it into a thick sheet, and cut it out into round cakes with the edge of a tumbler or a wine glass. Sprinkle a large iron pan with flour; lay the biscuits in it, cover it and set it to rise near the fire. When the biscuits are quite light, knead each one separately; prick them with a fork, and set them again in a warm place for about half an hour. When they are light again, bake them in a moderate oven. They should be eaten fresh, and pulled open with the fingers, as splitting them with a knife will make them heavy.
WHITE GINGERBREAD.
Sift two pounds of flour into a deep pan, and rub into it three quarters of a pound of butter; then mix in a pound of common white sugar powdered; and three table-spoonfuls of the best white ginger. Having beaten four eggs very light, mix them gradually with the other ingredients in the pan, and add a small tea-spoonful of pearl-ash melted in a wine glass of sour milk. Stir the whole as hard as possible. Flour your paste-board; lay the lump of dough upon it, and roll it out into a sheet an inch thick; adding more flour if necessary. Butter a large shallow square pan. Lay the dough into it, and bake it in a moderate oven. When cold, cut it into squares. Or you may cut it out into separate cakes with a jagging iron, previous to baking. You must be careful not to lay them too close together in the pan, lest they run into each other.
COMMON GINGERBREAD.—
Cut up a pound of butter in a quart of West India molasses, which must be perfectly sweet; sugar-house molasses will make it hard and heavy. Warm it slightly, just enough to melt the butter. Crush with the rolling-pin, on the paste-board, half a pound of brown sugar, and add it by degrees to the molasses and butter; then stir in three table-spoonfuls of ginger, a large tea-spoonful of powdered cloves, and a tea-spoonful of powdered cinnamon. Add gradually sufficient flour to make a dough stiff enough to roll out easily; and lastly, a small tea-spoonful of pearl-ash melted in a little sour milk. Mix and stir the dough very hard with a spaddle, or a wooden spoon; but do not knead it. Then divide it with a knife into equal portions; and, having floured your hands, roll it out on the paste-board into long even strips. Place them in shallow tin pans, that have been buttered; either laying the strips side by side in straight round sticks, (uniting them at both ends,) or coil them into rings one within another, as you see them at the cake shops. Bake them in a brisk oven, taking care that they do not burn; gingerbread scorching sooner than any other cake.
To save time and trouble, you may roll out the dough into a sheet near an inch thick, and cut it into round flat cakes with a tin cutter, or with the edge of a tumbler.
Ground ginger loses much of its strength by keeping. Therefore it will be frequently found necessary to put in more than the quantity given in the receipt.
