What Does the Peanut Butter Shot Consist Of? (Cocktail & Military Version)

4 min read

The phrase "peanut butter shot" has two starkly contrasting meanings, one being a popular, dessert-like cocktail and the other, a historically painful military antibiotic injection.

Quick Summary

This article explains the components and context behind the two very different things known as a peanut butter shot: a sweet cocktail made with peanut butter whiskey and Kahlúa, and a viscous bicillin injection given to military recruits.

Key Points

  • Dual Meaning: The term "peanut butter shot" refers to both a sweet cocktail and a painful military antibiotic injection.

  • Cocktail Ingredients: The most common cocktail recipe consists of equal parts Skrewball Peanut Butter Whiskey and Kahlúa coffee liqueur.

  • Military Context: In the military, the nickname refers to a Bicillin injection, a long-acting penicillin given to recruits.

  • Consistency is Key: Both the cocktail's appearance and the antibiotic's viscous nature give the shot its distinctive name.

  • Common Variations: Other versions of the cocktail exist, such as the Payday shot (with butterscotch) and the PB&J shot (with raspberry liqueur).

  • Painful Origin: The military shot is famously painful because its thick consistency makes it disperse slowly within the muscle tissue.

The Dual Meaning of 'Peanut Butter Shot'

When someone mentions a "peanut butter shot," the context is everything. For a bartender, it's a simple, sweet cocktail. For a military veteran, it conjures memories of a mandatory, and often painful, injection. The nickname in both cases comes from the resemblance to the thick, creamy consistency of peanut butter. This article will explore both the delicious and the dreaded versions of the peanut butter shot, detailing their ingredients, preparation, and background.

The Cocktail Version: Ingredients and Preparation

The most common version of the peanut butter shot is a two-ingredient alcoholic concoction cherished for its rich, nutty flavor. The classic recipe is simple and decadent, combining a peanut butter-flavored whiskey with a coffee liqueur.

Classic Peanut Butter Shot Recipe

  • Ingredients
    • 1 part Skrewball Peanut Butter Whiskey
    • 1 part Kahlúa Coffee Liqueur
    • (Optional) Garnish with a sprinkle of salt or crushed peanuts
  • Instructions
    • Fill a cocktail shaker with ice.
    • Pour in equal parts Skrewball Peanut Butter Whiskey and Kahlúa.
    • Shake well until thoroughly chilled.
    • Strain the mixture into a shot glass.
    • Serve and enjoy immediately.

The resulting shot is smooth, sweet, and tastes remarkably like a peanut butter cup in liquid form. The coffee notes from the Kahlúa perfectly complement the savory, nutty richness of the whiskey, creating a balanced and indulgent treat.

Popular Variations

For those who enjoy a little variety, there are several other interpretations of the peanut butter shot, often with additional ingredients to evoke a different flavor profile.

  • Payday Shot: This version adds a caramel element. Ingredients typically include peanut butter whiskey, butterscotch schnapps, and Irish cream liqueur to mimic the flavor of a PayDay candy bar.
  • Peanut Butter Cup Shot: To enhance the chocolate flavor, this recipe adds chocolate liqueur and often uses chocolate syrup to coat the inside of the shot glass before straining in the chilled cocktail.
  • PB&J Shot: This variation swaps the coffee liqueur for a fruit-based one, such as black raspberry liqueur (like Chambord), to create a flavor reminiscent of a peanut butter and jelly sandwich.

The Military/Medical Version: The "Bicillin" Shot

Long before peanut butter-flavored whiskey hit the market, the term "peanut butter shot" was used by military recruits to describe a notoriously painful medical injection. This injection is not a beverage, but rather a long-acting form of penicillin known as Bicillin. It was historically administered to recruits during basic training to prevent illnesses like "boot camp flu".

Why Was it Nicknamed the Peanut Butter Shot?

The nickname comes from two key characteristics of the injection:

  • Consistency: The antibiotic solution, Bicillin, is thick and viscous, much like peanut butter. This thick consistency is what makes it a long-acting medication, as the body absorbs it slowly over time.
  • Painful Injection: Due to its thickness, the injection is administered with a large-gauge needle into a large muscle, typically the buttocks. The fluid disperses slowly within the muscle tissue, causing a painful sensation and a lingering soreness that could last for days.

This mandatory rite of passage in the military has been the subject of countless recruit stories, highlighting the profound contrast in what the term "peanut butter shot" means to different audiences.

Comparison Table: Cocktail vs. Military Shot

Feature Cocktail Version Military (Bicillin) Version
Purpose A fun, dessert-like alcoholic beverage A mandatory antibiotic injection for recruits
Primary Ingredients Peanut butter whiskey, coffee liqueur Bicillin (a form of penicillin)
Consistency Smooth, creamy liquid Thick, viscous suspension
Administration Poured into a shot glass and consumed orally Injected intramuscularly with a large-gauge needle
Taste/Sensation Sweet, nutty, dessert-like Extremely painful and causes lingering soreness
Origin Modern cocktail creation Longstanding military medical practice

Tips for Crafting the Perfect Cocktail

If you're interested in the cocktail version, here are a few tips to ensure a top-tier result:

  • Chill Your Ingredients: For a truly refreshing shot, chill both your Skrewball and Kahlúa in the refrigerator beforehand. This helps create a thicker, colder drink that's perfect for sipping.
  • Use Good Whiskey: While Skrewball is the most recognized brand, several other options, like Sheep Dog or SQRRL, are also available. Experiment with different brands to find the flavor profile you prefer.
  • Shake Vigorously: Don't be shy with the shaker. A good, hard shake with plenty of ice is key to achieving a perfectly chilled and frothy texture.
  • Garnish for Impact: A simple sprinkle of crushed peanuts on top adds a pleasant crunch and enhances the visual appeal, elevating the drink from a simple shot to a mini cocktail experience.
  • Consider a Layered Effect: For a more visually appealing shot, you can create a layered effect by pouring the Kahlúa first and then slowly layering the peanut butter whiskey over the back of a teaspoon.

Conclusion: A Tale of Two Shots

The next time you hear someone mention a "peanut butter shot," you'll know there's more to the story than meets the eye. The term embodies two completely different experiences, from a sweet, satisfying cocktail to a challenging military tradition. While the alcoholic version offers a taste of liquid dessert, the medical version is a reminder of the historical realities of military life. Both, however, draw their name from the same common observation: the unmistakable consistency and color of peanut butter. By understanding the context, you can appreciate the richness of the classic cocktail or sympathize with the memories of those who received the medical version.

Frequently Asked Questions

No, the term "peanut butter shot" can refer to a sweet cocktail or a military antibiotic injection. The context is crucial for understanding which version is being discussed.

The classic peanut butter shot consists of equal parts Skrewball Peanut Butter Whiskey and Kahlúa Coffee Liqueur, shaken with ice and served.

The military injection, a form of penicillin called Bicillin, has a thick, viscous consistency similar to peanut butter, and is injected intramuscularly.

A PB&J shot is made with peanut butter whiskey and black raspberry liqueur, which gives it a fruity flavor reminiscent of a peanut butter and jelly sandwich.

Bicillin is a long-acting penicillin antibiotic given to military recruits to help prevent widespread bacterial infections and illnesses like the "boot camp flu".

The use of the Bicillin shot in military training has varied over time, but reports suggest it was still being administered as of recent years. Recruits with a verified penicillin allergy are given an alternative.

For the best result, chill all ingredients beforehand. Shake the mixture vigorously with ice to ensure it is very cold and frothy, then strain into a shot glass. A garnish of crushed peanuts adds a nice touch.
