method
1. Working over a bowl to catch the juice, halve the grapefruit, then cut out the segments between the membranes. Weigh out and reserve 85 g (3 oz) segments. Squeeze and measure out 85 ml (3 fl oz) juice from the remaining grapefruit segments.
2. Put the grapefruit juice, water, vinegar and sugar into a small saucepan over a medium heat and bring to the boil.
3. Gradually add the cornflour mixture, stirring constantly, and cook until thickened. Remove from the heat and add the reserved grapefruit segments, raspberries, wasabi paste and oil.
4. Using a hand-held electric blender, blend the mixture until smooth, or use a food processor. Pass through a fine sieve. Cover with clingfilm to prevent a skin forming and chill in the fridge. Keep the dressing in the fridge until ready to use.
5. Use with shredded vegetables or fruits to make a delicious salad, or as a sauce to accompany salmon dishes.
