In a pinch, it doesn’t really matter whether you get your ice from an ice tray or a convenience-store freezer—you’re probably just happy to have a drink that’s cooler than room temperature. But if you’re throwing a swanky party and want to impress, ice sphere molds produce large circular cubes worthy of pricey five-star cocktails that look too beautiful to consume. One cube per drink is all you need to maximize both the cooling and the coolness factors. There are scientific benefits, too. The jumbo sphere-shaped ice cubes melt more slowly than regular ones, so it won’t quickly dilute the taste and potency of your cocktail. Cheers!
