Preparation
Step 1
Bring half-and-half with caraway seeds just to a boil in a 3-quart heavy saucepan, then remove from heat and let steep, uncovered, 30 minutes.
Step 2
While caraway seeds steep, simmer prunes, vodka, and 1/2 cup sugar in a 1-quart heavy saucepan, partially covered, until prunes are tender, about 15 minutes. Cool slightly, then purée mixture in a blender, scraping down sides occasionally (use caution when blending hot liquids), until smooth.
Step 3
Whisk together yolks and remaining cup sugar in a bowl, then add half-and-half (do not strain) in a stream, whisking. Pour custard into 3-quart saucepan and cook over moderately low heat, stirring with a wooden spoon, until it registers 170°F on thermometer, about 8 minutes. Immediately pour custard through a fine-mesh sieve into a metal bowl and whisk in prune purée and vanilla. Chill, stirring occasionally, 30 minutes.
Step 4
Freeze custard in ice cream maker (in batches if necessary), then transfer to an airtight container and put in freezer to harden, about 12 hours.
