1 and 3/4 cup Plain flour
1 and 1/2 cup Fine semolina
1 Tsp Baking powder
1 Tsp salt
1 and 1/2 cup warm water
Just mix it all together, you don't want it sticky
Roll through the pasta roller all the way to lowest setting and place on cling-filmed tray in layers to freeze till needed.
I cook at 450F. Get a tray hot in the oven for a while then put the sheet on and cook from frozen till golden and crispy - 2-3 mins.
