Form A Lattice Top
Roll the remaining pastry into a large rectangle and cut into 1cm wide strips.
Remove alternate vertical strips and put them to one side.
Fold every other strip that remains back over onto itself and in half.
Lay one of the pieces that you removed perpendicular to the vertical strips and just above the folds.
Fold the vertical pieces back to where they were, then fold back the ones that you didn’t previously.
Lay another strip horizontally and keep repeating until you have a lattice. (Best watch the video to make it clear)
