Salt to taste Melt butter in saucepan, saute apple and shallots until soft. Add curry powder and cook for a minute longer. Stir in flour, add apple juice. Bring to boil, stirring constantly. Add salt and dill, simmer for 5 minutes. Add prawns and scallops, cook until almost tender, add banana 5 minutes before end of cooking time. Stir in cream, heat through. Serve with fluffy or fragrant rice. NB In this as in many recipes I use evaporated skim milk in lieu of the cream, and thicken if necessary. Better for the arteries, with no great compromise in taste or texture.
