Old Ratio: Equal parts Cherry Heering, blended Scotch, sweet vermouth, and orange juice
New Ratio: 1 part Cherry Heering, 2 parts blended Scotch (such as Chivas), 1 part sweet vermouth, 1⅓ parts orange juice
The Reasoning: Tasted with the traditional ratio, “it’s like there’s no Scotch in it,” says Shapiro. ”It could be anything. It’s like dessert in a glass.” The new version, however, “is still sweet, but you can taste Scotch in it.”
