You must have a care to work up your paste as soon as it is made, because it drieth up sooner than you are aware, and when it is dry, it is unusefull, because your sheets must be as thin as cobwebs, therefore you must choose a moist place.
Basically this is describing using phyllo dough, and the adjuration to work it in a moist place is imperative. Thaw your dough in the fridge and place your 12 sheets of dough between waxed paper with a moist towel laid over the top. Remove one sheet at a time and recover the rest immediately. Lay your dough in a pan and brush with melted butter, one layer at a time.
Prepare a mixture of 5 oz of pounded almonds, 4 oz of sugar and 2 eggs. Pour into your pan and cover with 6 more layers of dough brushed with melted butter. You could also use beurre cream or a cream cheese mixture with sugar and eggs.
Bake at 425°F for 5 minutes; then reduce temperature to 400°F and bake for 10-20 minutes more until golden brown and a broom straw inserted in the center comes out clean.
Removed from oven and sprinkle with orange or rose flower water and a sprinkle of sugar. Cool, slice and serve.
