The fizzers, which start out as innocent little balls of real cocktail ingredients (the exact recipe is proprietary), come in seven different flavors: Passion Fruit and Jalapeño, Cayenne and Blackberry, Orange Marmalade and Sherry, Tomato and Thyme, Pickled Plum and Kelp Tea, Lychee and Chia Seeds, and Celery and Elderflower. When dropped into a glass of tequila, simple syrup and soda water, the salt and citrus compound within the balls cause them to effervesce into a colorful, bubbly cocktail that’s ready to drink once the bubbles (somewhat) calm down. “We wanted to create something that was fun and whimsical,” says Goldstein. “We wanted to create something that was interactive and different. We wanted to think outside of the box.” Each fizzer has its own unique flavor, color and fizz. They’re the result of, in Goldstein’s words, “a lot of trial and error, a lot of science, and a lot of mistakes.” It was well worth the effort, though. The balls are packed with bright flavors that work perfectly with the tequila and, let’s face it, they’re just plain fun to watch.
