The pickling liquid from jarred peperoncini provides the ideal kick of heat in this golden version of the Mary, made with yellow tomatoes.
Puree tomatoes in a food processor until smooth. Strain in a cheesecloth-lined fine sieve set over a bowl, then press on solids to extract juice. (You'll need at least 2 cups.) Refrigerate until chilled, about 2 hours.
Stir together tomato juice, vodka, pickling liquid, and lemon juice. Divide among 4 ice-filled glasses, and garnish each with a peperoncino.
Pureed tomatoes can be strained overnight in the refrigerator. Sunny Marys can be refrigerated for up to 4 hours. Pour over ice just before serving.
