Step 8:
I found this bit very difficult. Take half of the dough and roll it out to make a 50cm * 20cm rectangle. The recipe now says to cut this in half lengthwise, and then to cut each strip into 5 parts, but I found I only had enough dough for 4. Then, cut a line of three 2cm slits along the middle of each part. Make three more rows of slits either side of the middle row, but offset them to produce a lattice effect (think how bricks are offset in buildings).
