Some colleagues and I were recently confronted with a list of Kahlua-based cocktails and asked to choose one. The usual suspects were there: White Russian, Black Russian, etc. Then there was the Kahlua Sour. The coffee liqueur paired with lemon juice and simple syrup. We all looked at each other in disbelief. Ew. What could be worse? We had to order it!
Our morbid curiosity was rewarded. It wasn't horrible. It was great. The best Kahlua cocktail I've had. We all agreed—it was delicious and we wanted another. The Kahlua Sour seems to be one of those counter-intuitive cocktails that—like the Blood and Sand—looks horrible on paper, but tastes great in the glass. You wouldn't think of squeezing some lemon in your morning coffee, would you? But the lemon cuts through both the thickness and sweetness of the coffee liqueur in a wonderful way, slimming it down, sparking it and lightening it up. Though Kahlua might seem the last thing you think of when you think light, summer drinking, I suggest you give it a try.
1 1/2 oz. Kahlua
1 oz. fresh lemon juice
1/2 simple syrup
Combine ingredients over ice. Shake. Strain into rocks glass.
