-ORgrated Cheddar cheese Pre-heat oven to 80 C, 180ºC , Gas mark 4. Lightly grease 8 individual pie dishes or ovenproof pudding bowls. Drain the can of salmon and make the juice up to 200ml / -10ºC l.oz. with water for fish stock. Flake the salmon. Set aside. Brush each individual sheet of filo pastry with oil and fold into sixteen 12.5cm / 13 cm squares. Put one square into each pie dish leaving the pointed corners protruding over the edge. Brush with oil then put a second square of pastry onto the first, but with the corners pointing up in between the original ones to create a water lily effect. Brush the points well with oil then bake for 5 minutes to set but not brown. Take out of the oven. Reduce the oven temperature to 150 C, 150ºC , Gas mark 2. Melt the margarine and stir in the flour.
