- 1 pound beefsteak tomatoes, cut into 2-inch wedges
 - 1/2 cup cream Sherry
 - 1 teaspoon sugar
 - 1 tablespoon plus 1/2 teaspoon Sherry vinegar, divided
 - 2 celery ribs
 - 1/2 seedless cucumber
 - 2 large radishes
 - 1/2 teaspoon extra-virgin olive oil
 
- Blend together tomatoes, Sherry, sugar, 1 tablespoon vinegar, and 1/4 teaspoon each of salt and pepper in a blender until smooth. Strain through a fine-mesh sieve into a bowl, pressing on and then discarding solids.
 - Pour tomato mixture into an 8- to 9-inch nonreactive baking dish and freeze until partially frozen, about 1 hour. Scrape and stir with a fork, crushing any lumps. Continue to freeze, scraping once or twice, until evenly frozen, about 2 hours more.
 - Cut celery, cucumber, and radishes into fine julienne strips, then toss in a bowl with oil, remaining 1/2 teaspoon vinegar, and salt and pepper to taste.
 - Serve granita with vegetable julienne.
