Avocado Cream

3 ripe avocados
1/2 C + 2 T sugar
Juice of 1 lime
6 T milk
Pinch salt
3 T port wine

Peel and chop the avocados. Place in a small bowl and sprinkle with lime juice and sugar. Cover and chill for 15 minutes. In a blender or food processor, blend the avocado mixture with the milk and salt until smooth. Pass through a sieve, pressing with the back of a spoon. Stir in the port and serve, well-chilled, in dessert glasses.
