From Charmaine Solomon's Encyclopedia of Asian Food, Periplus Editions,1998 I'm always on the lookout for durian recipes and this is a good one.
If using frozen durian, thaw completely.
Remove seeds and press flesh through a nylon sieve to eliminate the fine fibres.
Heat milk and cream in a heavy enamel or other non-aluminium pan, stirring until almost boiling.
Whisk egg yolks with Sugar until light, stir in a ladleful of the hot milk mixture and return to saucepan.
Stir over very low heat until custard thickens, taking care not to let it boil or it will curdle.
Cool the custard and chill it well, then add a little at a time to the durian pulp, combining it thoroughly before adding more custard.
This keeps the texture even.
Freeze in a churn or in a shallow glass dish.
If using still-freezing method, stir 2 or 3 times during freezing to enhance smoothness.
Or, after it has frozen, break into pieces and purée in food processor until smooth but not melted.
Return to freezer until firm.
Press freezer wrap directly on surface of ice cream to prevent ice crystals forming.
It is advisable to store durian ice cream in a freezer container with a well-fitting lid.
