You can use the Perlini system to carbonate cocktails and other drinks that won’t work in a traditional home carbonation system, thanks to the large opening of the three-part cobbler-style shaker. I even used it to carbonate some fresh strawberries. It comes with excellent instructions (printed, and on a USB drive) that include recipes, solid explanations of the science of carbonation, a formula to calculate optimal booze-to-ice ratios, and other important mixological physics.
