Whisk four strained or well-cleared eggs to the lightest possible froth (French eggs, if really sweet, will answer for the purpose), and pour to them, by degrees, a pound and a quarter of treacle, still beating them lightly. Add, in the same manner, six ounces of pale brown sugar free from lumps, one pound of sifted flour, and six ounces of good butter, just sufficiently warmed to be liquid, and no more, for if hot, it would render the cake heavy; it should be poured in small portions to the mixture, which should be well beaten up with the back of a wooden spoon as each portion is thrown in: the success of the cake depends almost entirely on this part of the process. When properly mingled with the mass, the butter will not be perceptible on the surface; and if the cake be kept light by constant whisking, large bubbles will appear in it to the last. When it is so far ready, add to it one ounce of Jamaica ginger and a large teaspoonful of cloves in fine powder, with the lightly grated rinds of two fresh full-sized lemons. Butter thickly, in every part, a shallow square tin pan, and bake the gingerbread slowly for nearly or quite an hour in a gentle oven. Let it cool a little before it is turned out, and set it on its edge until cold, supporting it, if needful, against a large jar or bowl. We have usually had it baked in an American oven, in a tin less than two inches deep; and it has been excellent. We retain the name given to it originally in our own circle.
