          Method: 
          Mix together the flour and salt in a 
          bowl. Cut 50 g/2 oz of the butter or margarine into pieces, then rub 
          into the flour until the mixture resembles breadcrumbs. Add the lemon 
          juice and water and mix with a round-bladed knife to a soft dough. 
          Turn the dough on to a lightly floured surface and knead gently until 
          smooth. Shape into a ball and cut a deep cross in the centre, cutting 
          about three-quarters of the way through the pastry (paste). Open out 
          the flaps and roll the pastry so that the centre remains thicker than 
          the edges. Place the remaining butter or margarine on the centre of 
          the pastry, fold the flaps over to cover it and seal the edges. Roll 
          out the pastry to a 40 x 20 cm/ 16 x 8 in rectangle, being careful not 
          to let the butter leak out. Fold the bottom one-third of the pastry up 
          to the centre, then fold the top one-third over that. Press the edges 
          together to seal, then give the pastry one quarter turn. Cover with 
          clingfilm (plastic wrap) and chill for 20 minutes. Repeat the rolling, 
          folding and chilling 6 times in all. Cover with clingfilm and chill 
          for 30 minutes before use. |
