A Brussels recipe.
Pound down flour, brown sugar, butter, nutmeg, mace and cinnamon in powder. Add, as well, bicarbonate of soda. Make the paste into a ball, and cover it with a fine linen or muslin cloth, and leave it till the following day. If you have no molds to press it in, cut it into diamonds or different shapes, and cook them in the oven on buttered trays. I believe waffle irons can be bought in London.
