Ingredients
Preparation
Step 1
With a knife halve vanilla beans lengthwise. Scrape seeds into a large heavy saucepan and stir in pods, cream, milk, and sugar. Bring mixture just to a boil, stirring occasionally, and remove pan from heat.
Step 2
In a large bowl lightly beat eggs. Add hot cream mixture to eggs in a slow stream, whisking, and pour into pan. Cook custard over moderately low heat, stirring constantly, until a thermometer registers 170°F. (Do not let boil.) Pour custard through a sieve into a clean bowl and cool. Chill custard, its surface covered with wax paper, at least 3 hours, or until cold, and up to 1 day.
Step 3
Freeze custard in an ice-cream maker, in 2 batches if necessary. Transfer ice cream to an airtight container and put in freezer to harden. Ice cream may be made 1 week ahead.
