Cold water * do not use shortening. (This is a slight variation from the pie dough that I have made all my life--I tried it during the holidays, and this is a definite keeper for me. Comments: I would end up with 6 to 8-9 inch pie shells (tops and bottoms). However, this pastry works well for mini pie shells (I made 18 mini pies with my piemaker). Of course, pies can be made individually and the remainder just covered well and stored in refrigerator. Measure flour, sugar, salt and baking powder into large bowl. Cut in lard until the size of tiny peas. I dig right in with my hands and this makes the job easier. Break egg into measuring cup and beat with fork until frothy and add vinegar to egg mixture. Add enough water in same cup to equal 1 cup. Pour a little at a time over flour mixture and continue to work pie dough with hands--continue this until all liquid is absorbed. Divide into four balls. Wrap and refrigerate. Store in refrigerator up to two weeks or in freezer for longer period. Most often, I make my pie shells immediately and do not put the dough in the refrigerator. If dough is too moist to work with add a very little flour. In addition, there will be extra flour on your board to roll the pastry.JM. SOURCE COMPANYS COMPANY--PIES (BY JEAN PARE) 1992 ----
