Allow the pastry to come to room temperature (the jus-roll variety only takes about 10 minutes). Unroll on a work surface lightly dusted with flour and roll until it is a little thinner. Cut into 6 squares and use each piece to line 6 x 4" (6 x 10cm) round, fluted, loose-bottom greased flan tins. Trim the edges and place a circle of greaseproof paper in each. Fill with baking beans and bake "blind" for 10 minutes. Remove the paper and beans and return the times to the oven for another 2-3 minutes. Remove from the oven and allow to cool slightly. Reduce the oven to 180oC/360oF.
Whisk the eggs and the egg yolk with the cream, cayenne pepper, lemon juice, parsley and seasoning. Place the pastry cases on a baking try and divide the crabmeat between each one, then pour over the egg mixture to three quarter fill the cases. Sprinkle each with Parmesan. Bake for 15-20 minutes, until the filling has risen slightly and is just firm to the touch.
Allow to cool*.
*Remember if packing for a picnic to chill completely before putting in an airtight container.
