Directions:
Into one quart of sifted flour mix two teaspoonfuls of baking powder and a teaspoonful of salt; then sift again. Measure out one teacupful of butter and one of lard, hard and cold. Take the lard and rub into the flour until a very fine smooth paste. Then put in just enough ice-water, say half a cupful, containing a beaten white of egg, to mix a very stiff dough. Boll it out into a thin sheet, spread with one-fourth of the butter, sprinkle over with a little flour, then roll up closely in a long roll, like a scroll, double the ends towards the centre, flatten and re-roll, then spread again with another quarter of the butter. Repeat this operation until the butter is used up. Put it on an earthen dish, cover it with a cloth and set it in a cold place, in the ice box in summer; let it remain until cold; an hour or more before making out the crust. Tarts made with this paste cannot be cut with a knife when fresh; they go into flakes at the touch.

You may roll this pastry in any direction, from you, toward you, sideways, any way, it matters not, but you must have nice flour, ice-water and very little of it, and strength to roll it, if you would succeed.
