Grapefruit And Cassis Sherbet

Preparation

1. Step 1

   Carefully peel and section the grapefruit over a bowl, saving the juice. Cut away and discard all the outer white membrane and connecting membrane. To section them, run a knife between each segment. Discard any seeds. There should be about three cups of flesh and one cup of juice.

2. Step 2

   Combine the grapefruit sections and juice in a food processor or blender and blend as thoroughly as possible. There should be about three and one-third cups. Put the mixture in a mixing bowl.

3. Step 3

   Combine the sugar with two cups of water in a saucepan and bring to a boil. Cook about five minutes and cool completely. Add to the grapefruit mixture and blend. There should be about five and one-half cups. Add the cassis and chill thoroughly.

4. Step 4

   Pour the mixture into an electric or hand-cranked ice-cream freezer and freeze according to the manufacturer's instructions. When the mixture starts to freeze, add the egg white and continue freezing to the desired consistency.
