1 lb. flour.
¾ lb. butter.
1 egg; use the yolk only.
Ice-water.
Chop half the butter into the flour; stir the beaten egg into half a
cup ice-water, and work the flour into a stiff dough; roll out _thin_,
baste with one-third the remaining butter, fold closely, roll out
again, and so on until the butter is used up. Roll very thin, and set
the last folded roll in a very cold place ten or fifteen minutes before
making out the crust. Wash with beaten egg while hot. This paste is
very nice for oyster-_pâtés_ as well as for fruit-pies.
