Spiced Tamarind Sour
About
The Spiced Tamarind Sour is the whisky sour as it might have been invented in India, and once you taste it, you wonder why it wasn't. The classic runs on whisky, citrus, and sugar. This version keeps the whisky, India's spirit of choice, and rebuilds the rest around the country's own idea of sweet-and-sour: imli for the tang, jaggery for a deep, caramel sweetness, and a whisper of warm spice to tie it together. The result is nostalgic and refined at once, a drink that tastes both brand new and like something you've always known.
The intelligence of it is that Indians already love this flavor profile, they just meet it in chutney rather than a cocktail. Tamarind's dark, fruity sourness and jaggery's molasses depth are the backbone of half the country's street food, so putting them behind whisky feels less like an experiment and more like a homecoming. Lemon keeps it bright, bitters add complexity, and pineapple juice lends the silky froth that gives a proper sour its elegance.
Bold, balanced, and quietly clever, it's the drink that proves an Indian palate and a classic cocktail were never as far apart as they seemed.
Shaken or Stirred? Shaken, hard. Pineapple juice is what gives this sour its body and its fine, silky froth, and a firm 12 to 15 second shake is what draws that texture out while chilling and combining everything. The drink is then double strained over ice for a clean, smooth finish. This is a sour, and the texture is half the point, so the shake is non-negotiable.
What You'll Need
For one Spiced Tamarind Sour:
- 60 ml Indian whisky or bourbon
- 22 ml tamarind (imli) syrup
- 15 ml fresh lemon juice
- 15 ml jaggery syrup
- 1 egg white
- 2 dashes Angostura bitters
- Ice Cubes
Glass: Rocks
Garnish: Lemon wheel and a smoked cinnamon stick
Pro tip: Give the egg white a proper dry shake, without ice, before you add anything cold. This first shake is what whips the egg white into the fine, stable foam that defines a good sour. Skip it or rush it and you get a thin, patchy head instead of that clean, silky cap. The dry shake is the single most important step for texture. juice froths better than carton, and it brings a brighter tropical note that flatters the tamarind.

Using Barsys Cocktail Machine?
This is a shaken sour with several strong, competing ingredients, which makes it a natural for the Shaker Pro. Tamarind syrup is intensely tangy and jaggery syrup is intensely sweet, so the drink stands or falls on the ratio between them, the imli, the jaggery, and the lemon all pulling in different directions at once. The Shaker Pro's illuminated base guides each pour to under a millilitre, so those measures land exactly right and the sweet-sour balance holds rather than swinging to one extreme.
Then the built-in motor delivers the firm, sustained shake a good sour requires, the agitation that whips the pineapple juice into a silky froth and integrates every element. Judging that shake by hand is guesswork; the Shaker Pro makes the texture reliable rather than hit-or-miss. Guided on the pour, shaken to a smooth, elegant finish, and portable enough to bring a refined sour to any showcase floor. For a drink this dependent on both precise ratio and proper texture, it handles the two hardest parts at once.

Tasting Notes
The Barsys Edge
The Spiced Tamarind Sour is a balancing act between two powerful opposites: the sharp, dark sourness of tamarind and the deep, molasses sweetness of jaggery. Pour either by eye and the drink lurches, too much imli and it turns aggressively sour, too much jaggery and it slumps into heavy sweetness. Add the lemon and bitters, and there are multiple potent ingredients that all have to sit in precise proportion for the sour to work.
Barsys keeps that proportion exact, and adds a second advantage the classic version can't guarantee by hand: a consistent shake for a consistent texture. The guided pour locks in the sweet-sour ratio, and the motor delivers the same silky foam every time. In a drink defined by tension between strong flavors and by the elegance of its finish, precision is what makes it repeatedly excellent rather than occasionally lucky.
Sip Setting
The Spiced Tamarind Sour is an evening drink with real presence, made for slower, later moments and for premium events that want depth in the glass rather than just refreshment. Its silky texture and layered sweet-sour-spice profile reward sipping, and its nostalgic tamarind heart makes it a talking point for any Indian guest. It's equally at home as a sophisticated after-dinner pour or the standout on a showcase menu, the drink people describe to others long after the evening ends.
Garnish Game
A lemon wheel signals the citrus brightness cutting through the drink's dark, sweet depth. The smoked cinnamon stick is the finishing flourish, its gentle wisp of smoke adding an aromatic, warming note that meets the nose before each sip and reinforces the drink's spiced character. Together they frame a cocktail that's rich and complex, previewing the warmth and brightness within. A considered, faintly theatrical finish for a considered drink.

FAQs
What is a Spiced Tamarind Sour?
An Indian twist on the classic whisky sour, made with whisky, tamarind (imli) syrup, jaggery, fresh lemon, egg white, and bitters, shaken to a silky finish and served over ice. It's also known as an Imli Jaggery Whisky Sour.
What does it taste like?
Sweet, sour, and spiced, with dark tangy tamarind, deep caramel jaggery, warm whisky, and a bright lemon lift, all carried on a silky texture. It drinks like tamarind chutney reimagined as an elegant cocktail.
Can I make it without egg white?
Yes. Use 45 ml pineapple juice instead. It creates a similar silky froth naturally, suits vegetarians, and adds a subtle tropical sweetness that complements the tamarind.
What whisky should I use?
A smooth Indian whisky keeps it authentic and works beautifully, while bourbon adds a rounder, sweeter, vanilla-forward depth. Both suit the drink; the choice comes down to how bold you want the base.
Can I make it without alcohol?
Yes. Skip the whisky and build the tamarind, jaggery, lemon, and bitters over soda, with pineapple juice for texture, for a spiced tamarind mocktail sour.
