Like normal shortcrust but with a bit of sugar as well.  Sam and I made jam tarts (Asda extra deluxe strawberry jam); Hannah sieved some flour and then decided she didn’t want to do any more.  John said he’d never made jam tarts, revealing that he had a deprived childhood.  We didn’t use a pie tin; we made edges for the tarts with extra circles having cut outs, and stuck on with milk.  The tarts were very tasty.
