How Forbidden Sour Tastes?

The Forbidden Sour is a complex blend of sweet, sour, and fruity flavors. The whiskey provides a strong, robust base, while the apple juice adds a sweet, fruity note. The lemon juice and simple syrup balance out the sweetness with a tart, sour edge.

Interesting facts about Forbidden Sour

  • The Forbidden Sour is a variation of the classic Whiskey Sour.
  • The addition of apple juice gives it a unique, fruity twist.
  • Despite its name, the Forbidden Sour is not actually 'forbidden'. The name is just a playful nod to its unique flavor profile.



Whiskey (2 oz) is the soul of many a man, and the heart of this cocktail. It adds depth, warmth, and a little bit of mystery—just like your ex. Too much, and you're in hangover town; too little, and the cocktail loses its backbone. Alternative: Try bourbon for a sweeter, fuller profile.

Apple Juice

Apple Juice (1 oz) brings a crisp and fruity flair to the mix, and not using it would be like watching 'Snow White' without the apple—bland and not as fun. If you replace it with pear juice, expect a softer, more floral drink.

Alex Green

Lemon Juice

Lemon Juice (1 oz) is the zesty spark that keeps the cocktail from becoming a snooze fest. Without it, you might as well be drinking apple-flavored whiskey on the rocks. Swap with lime juice for a sharper tang.

Simple Syrup

Simple Syrup (1/2 oz) is the sweet whisper that balances the acid and the alcohol, smoothing over potential conflicts like a good diplomat. Omitting it means welcoming unnecessary tartness. If you're out of simple syrup, honey syrup is a fine stand-in.

Egg White

Egg White (1) froths up the party and adds a silky texture—and what's a party without some smooth moves? If you skip it, the cocktail will lack body. Vegan? Try aquafaba for a near-identical effect.

Apple Slice

Apple Slice for garnish is all about looks because we eat with our eyes first. But also, it's a sneak preview of the apple flavor inside. No garnish means less fancy, but the taste remains uncompromised.

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.

Garnishing a bar drink depends on the type of garnish and the cocktail. Generally, it involves preparing the garnish (like cutting a citrus wheel or picking a sprig of mint), and then adding it to the drink in a visually appealing way (like perching it on the rim or floating it on top).
