Classic flaky pastry with layered fat.

Steps

1. Blend the 2 kinds of fat together and divide into 4 parts.
2. Add one part of the fat to flour, salt and lime juice. Rub fat in until the whole looks like bread crumbs.
3. Add enough cold water to make a fairly soft dough.
4. Roll out on a lightly floured board to a rectangular shape.
5. Put 1/4 of the fat in small parts or bits over the top 2/3 of the pastry.
6. Fold pastry bottom to middle and top to bottom. Seal edges with rolling pin.
7. Turn the pastry so that the fold is lengthwise of the board.
8. Roll out again. Mark in thirds and repeat steps 5, 6 and 7.
9. Roll out a 4th time, mark and fold as before but without any fat. Place dough in a covered plate, cover and leave in a cool place (fridge) for about 1 hr so that the fat cools.
10. Roll out and shape as required.
