Vanilla Custard Sauce Recipe

Directions:

1. Scrape seeds from vanilla bean into a 2- to 3-quart heavy saucepan with tip of a paring knife, then add pod and half-and-half and bring just to a boil. Remove from heat.
2. Whisk together eggs and sugar in a bowl until well combined, then add hot half-and-half mixture in a slow stream, whisking constantly. Transfer custard to saucepan and cook over moderately low heat, stirring constantly with a wooden spoon, until thickened and custard registers 175°F on thermometer, 5 to 10 minutes (do not let boil).
3. Pour custard through a fine-mesh sieve into a metal bowl, discarding solids. Set bowl in a larger bowl of ice and cold water and stir custard until cool. Chill in refrigerator, covered, until cold, at least 1 hour.
4. Cooks' note: Custard sauce can be chilled, covered, up to 2 days.
