Preparation Cut a small X in bottom of each tomato. Blanch tomatoes, 5 at a time, in a saucepan of boiling water 3 seconds. Immediately transfer with a slotted spoon to an ice bath to stop cooking. Drain and peel, transferring to a large shallow dish. Stir together vodka, vinegar, sugar, and zest until sugar has dissolved, then pour over tomatoes, gently tossing to coat. Marinate, chilled, at least 30 minutes and up to 1 hour. Stir together salt and pepper and serve with tomatoes for dipping. Cooks' note:Tomatoes can be peeled and vodka marinade prepared 1 day ahead and kept separately, chilled.
