The Slap Sour is a modern twist on the classic sour cocktail. It's designed for those who enjoy a punch of flavor in a small package.

  • Origin: The exact origin is unknown, but it's a product of the craft cocktail movement.
  • Popularity: It's a hit among patrons who seek a quick, flavorful drink.
  • Ideal for: Sour lovers and those looking for a bold taste without the volume of a full-sized cocktail.

How Slap Sour Tastes?

The Slap Sour is a vibrant, tangy shot with a harmonious balance between sour and sweet. The citrus notes are pronounced, giving it a zesty kick, while the underlying sweetness smoothens the overall experience.

Interesting facts about Slap Sour

  • The 'Slap' in Slap Sour refers to the sharp hit of sourness that greets the palate.
  • This shot is often used as a palate cleanser between drinks.
  • It's a popular choice for toasting due to its bold flavor and quick consumption.


Lemon Juice

Lemon juice brings the sour punch, it's the yin to our whiskey's yang. Too much, and you'll pucker more than a duckface, too little, and the drink's as flat as a pancake. Without it, you lose the 'sour' in Slap Sour.

Simple Syrup

The simple syrup is the sweet whisper that says, 'it's gonna be okay' to your taste buds. If you go overboard, you're in candyland; too shy, and you might as well be sucking on a lemon. No syrup, and the balance topples.

Whiskey is the heart of this concoction, giving warmth, depth, and that 'oak-y' hug. Skimp on it, and the shot becomes a shy wallflower; too generous, and it's a frat party in a glass. Without whiskey, it's just a sour mocktail.

Egg White

Egg white is our smooth operator, giving the shot a velvety mouthfeel. Less egg white, the drink's as thin as my patience on a Monday. More, and you're slurping a meringue. Skip it, and you lose the foamy crown.

Angostura Bitters

A dash of Angostura bitters is like that last-minute accessory you throw on that makes your outfit pop. Without it, the shot's just not complete. Adding too much could lead to a bitter coup d'état against the other flavors.

    • 0.5 oz lemon juice
    • 0.25 oz simple syrup
    • 1 oz whiskey
    • 0.5 oz egg white
  3. Dry shake to emulsify the egg white.

  • A dry shake (shaking without ice) is crucial for creating the frothy top.

Perfect Pairings

Food Pairings

  • Charcuterie Boards: A Slap Sour shot can cut through the richness of cured meats and cheeses, providing a refreshing palate cleanser.
  • Spicy Appetizers: The citrus and sweetness of the shot can balance the heat from dishes like buffalo wings or jalapeño poppers.
  • Dark Chocolate: For a dessert pairing, the complexity of whiskey and the sourness from the lemon juice complement the bitterness of dark chocolate beautifully.

Drink Pairings

  • Cold Brew Coffee: The bitterness of coffee and the sourness of the shot can result in an energizing contrast.
  • Craft Beer: A hoppy IPA could go nicely with the Slap Sour shot, as the bitterness of both could play well together.

In case you forgot basics how to make Slap Sour

The basic composition of simple syrup is relatively straightforward – a 1:1 ratio of sugar and water. This mixture is heated until the sugar dissolves, resulting in a clear, sweet syrup.

Add your ingredients to the shaker first, then ice. Fill it up to ¾ of its capacity to ensure enough space for shaking. Hold the shaker with both hands (one on the top and one on the bottom) and shake vigorously. The shake should come from your shoulders, not your wrists.

Learn everything on how to shake

Place your chosen strainer on top of the shaker or mixing glass, ensuring a secure fit. Pour the cocktail into a glass through the strainer, which will catch solid ingredients and ice. If double straining, hold the fine mesh strainer between the shaker and the glass.
