Seeds, juice, and
scraps from chopping
1-1/2 lb. ripe tomatoes
Seeds and juice from 1 large cucumber (8-10 oz.)
1 tbsp sugar
1/2 tsp kosher salt
1/2 tsp sherry vinegar
Pinch of cayenne pepper
Step 1: Put the tomato and cucumber seeds and juice in a fine-mesh strainer set over a small bowl. Add any other scraps from chopping, let drain, and then use a spoon to press the seeds and scraps to release more juices. You should end up with between 2/3 and 1 cup liquid.
Step 2: Bring 1/4 cup water to a boil in a small saucepan on the stove or place the water in a glass measuring pitcher and bring to a boil by heating in the microwave for 30 seconds. Add the sugar and salt, stir to dissolve, and add to the tomato-cucumber water along with the vinegar and cayenne. You can adjust seasoning if needed; it will taste sweet now, but this will dissipate with freezing.
Step 3: Place the mixture in an 8" x 8" glass baking dish and freeze for 30 minutes.
Step 4: Rake with a fork, breaking up any frozen crystals. Continue freezing and scraping every 30 minutes until slushy, about 1-1/2 hours total. (You can hold the granita an hour or two longer in the freezer if you stir it occasionally.) Serve in shot glasses with small spoons.
