Mary & Camillo: A Bloody Mary Negroni

Stir all of the ingredients with ice until chilled, strain into a glass holding a large ice cube, then garnish.
Tomato MixCombine 10 oz. of fresh or high-quality canned tomato juice, 1 1/2 oz. of fresh cucumber juice (blended and strained), 1/2 oz. of citric acid solution (10:1 water to powdered citric acid), 1/2 tsp. of sea salt, 8 drops of soy sauce, and 8 drops of Tabasco. Mix well and adjust to taste. In a saucepan over medium-high heat, heat the mixture to 160–165 degrees Fahrenheit, but do not boil. Maintain heat for at least 30 seconds to gently pasteurize. Cool the mixture, then strain through a cheesecloth-lined chinois, then again through a coffee filter. Bottle and keep refrigerated for use within 1 week
