Pre-heat the oven to 200c/400f/gas 6. Trim the tips off the asparagus to the length of 1 1/2 inches. Blanch in salted boiling water for 5 minutes then drain and refresh. Sift the flour into a mixing bowl along with a pinch of salt, add the butter and rub in. Add enough ice cold water to bind to a firm dough, turn out onto a floured surface and roll out to fit a 10 inch fluted flan dish. Bake blind in the oven at 190c/375f/gas 5 until set but not browned about 10-15 minutes. With a knife, stretch the bacon rashers on a flat surface, wrap a small piece around each asparagus tip. In a bowl mix the egg yolks with the cream, grated cheese and seasoning. Spoon onto the flan case and arrange the bacon and asparagus rolls in the custard. Turn the oven to 180c/350f/gas 4 and bake for 30-35 minutes or until the quiche is set and golden brown. Cool for 1 hour then serve.
