Roll out very thin and square some fine puff-paste, lay it on a tin or copper oven-leaf, and cover it equally to within something less than an inch of the edge with peach or apricot jam; roll a second bit of paste to the same size, and lay it carefully over the other, having first moistened the edges with beaten egg, or water; press them together securely, that the preserve may not escape; pass a paste-brush or small bunch of feathers dipped in water, over the top, sift sugar thickly on it, then with the back of a knife, mark the paste into divisions of uniform size, bake it in a well-heated but not fierce oven for twenty minutes, or rather more, and cut it while it is still hot, where it is marked. The fanchon-nettes should be about three inches in length and two in width. In order to lay the second crust over the preserve without disturbing it, wind it lightly round the paste-roller, and in untwisting it, let it fall gently over the other part.
This is not the form of pasty called by the French fanchonnettes.
Fine puff-paste, 1 lb.; apricot or peach-jam, 4 to 6 ozs.: baked 20 to 25 minutes.
