Remove both lots of dough from the fridge

Lightly dust with flour and laminate both using the widest setting on your pasta machine

Dust your surface with semolina

Place the white pasta down on the semolina and cut in half

Cut the red pasta into 4 equal lengths

Place two lengths of the red pasta on one length of the white pasta
