For the ice cream: beat yolks, sugar and glucose until the mixture is pale yellow. Infuse cream with smoked salmon and blend. Strain over the yolk mixture and add gelatin to dissolve. Churn in ice cream machine. (This needs to be done in advance.)
Briefly pan-sear the trout. Beat the meringue ingredients as you would for French meringue. Cover the trout with the meringue mix and bake at 180°C for 2-3 min.
Peel, remove the pith and brunoise the orange and grapefruit and put to one side. Whisk ginger, soya, mirin, sugar and oil. Spoon the emulsion into the centre of your serving bowl. Place trout on top, topped with citrus salsa, cucumber, smoked salmon ice cream and caviar.
