Wholemeal Shortbread

This recipe produced accusing cries of "Why have you never made this before?" so I reckon it is worth sharing.

8 oz wholemeal flour
6 oz butter
5 oz demerara sugar
pinch of salt

Rub the butter into the salted flour (I softened the butter for 30 seconds in the microwave first - check how powerful your microwave is first though!). Then add the sugar and knead with the hands until the mixture is soft. You are then supposed to roll it out to 1/2 inch thick, but I just pressed it into a baking tray, and I think it would be crisper if you made it less than 1/2 inch thick. Back at 375 degrees F/190 degrees C for 20 minutes, then cut into slices and cool on a rack.
