Makes 2 cocktails
4 oz. Whiskey (I prefer Rye Whiskey)*
2 oz. Lemon Juice**
1 oz. Simple Syrup**
2-3 dashes Aromatic Bitters
1 Large Egg White (1 oz if using pasteurized egg whites)
Maraschino Cherries for garnish
Combine ingredients in a cocktail shaker without ice, adding the egg white last. Shake vigorously without ice for about 20 seconds. This is called dry shaking, and it helps to incorporate the egg white without watering down the drink too much.
Add plenty of ice and shake again for 15-20 seconds more. Strain well into coupe glasses. Even if your shaker has a built in strainer, I like to double strain through a fine mesh strainer to remove any shards of ice or egg white.
Garnish each with a cocktail cherry.
*Bourbon is popular for whiskey sours, but I much prefer Rye Whiskey because it’s a bit less sweet and has a slight spiciness that compliments the lemon juice.
** To make simple syrup heat equal parts sugar and water until sugar is completely dissolved. Can be done in the microwave. Cool before use.
You can adjust the ratio of simple syrup and lemon juice in the cocktail to taste if desired.
The whiskey sour has a long history. It was probably developed as a scaled-down, individual version of a traditional citrus and whiskey punch.
Jerry Thomas included a recipe in his book in 1862, but even then the sour was probably a century old or more. His version didn’t include an egg white, but to me, it feels a little too simple without it. At some point people started adding soda to the recipe, but they stopped when they realized shaking the drink flattens the fizz.
The egg white was eventually added because it adds a frothy, creamy mouthfeel that really transforms the cocktail into something special. It goes down smoother and looks nicer in the glass too. We know that adding a raw egg white to a cocktail can make some people nervous, but as long as you’re using fresh, good quality eggs it really is safe for most people. You can also use pasteurized egg whites if you’d feel more comfortable.
After prohibition the whiskey sour waned in popularity for a few decades, but it came back in a big way in the 1950s and 60s. Unfortunately, this was also the era of convenience foods and food-product innovations, and the pre-prohibition era recipe that included fresh lemon juice, sugar, and egg white was replaced with sour mix.
Fortunately, in the late 1990s the craft cocktail movement began, and a vast number of classic cocktail recipes were resurrected. Since then, many bars ditched the sour mix for a recipe much like the one above.
