Strawberry Mousse

To a pint of double cream add the juice of a lemon and a cup of strawberry preserve. Beat until thick to the bottom of the bowl. Have ready a three-pint mould lined with lemon, orange or pineapple sherbet. Put the mousse mixture into the center and cover with more sherbet. Adjust the cover over paper and pack in equal parts of ice and salt. Let stand about two hours. Lining the mould with sherbet may be omitted, but it is a great improvement to the dish. Thus lined, it is removed from the mould with ease.
