The Forbidden Passion (Smirnoff Passion Fruit Vodka, Blueberry Schnapps, pureed strawberries, Zardetto prosecco, strawberry garnish; $10), one of Croma's more popular drinks, gets its deep, dark red color and thick consistency from the strawberries. It looks like it's made from actual food. In fact, it seems like the product of pressing and stomping the fruits, like something you'd see in wine-making. The prosecco topper buoys the fruit along on a cascade of bubbles.
The Green Dragon (Stoli Ohranj Vodka, Cointreau, pureed mango, fresh orange juice, Midori, kiwi; $11), with its striking two-tone layers of melon and sun-kissed mango, is another fine use of puree. The Dragon is an abstract painting of a martini; its taste develops depending on the depth of your sip.
The Japanese Plum Ginger (Pearl Plum vodka, red wine, ginger, simple syrup, lime juice; $11) doesn't use purees, but it has organic textures of dark fruit from the merlot (red wines in cocktails aside from sangria should catch on) and spice from the fresh ginger coating the glass. Like many of Croma's cocktails, it drinks like something that actually came from the earth.
