Amaretto Sour Recipe — Almond, Lemon & a Bourbon Upgrade
The Amaretto Sour is a 1970s classic that spent decades tasting like candy — until bartender Jeff Morgenthaler proved the fix was more acid, more proof, and an optional egg white. Amaretto is low-proof and sweet, so the drink only balances when lemon leads and bourbon backs it up.
What Makes It Special
Sweetness without structure collapses on the palate. Lemon's citric acid sharpens the almond notes while bourbon's higher proof and oak tannins give the mid-palate something to grip. The optional egg-white dry shake adds a silky cap that carries aroma — the same emulsion trick that makes a Whiskey Sour feel luxurious.
What Makes It Special
This classic cocktail is particularly beloved for its unique blend of flavors and elegant presentation.
Ingredients
- 1 1/2 oz (45ml) Amaretto
- 3/4 oz (22ml) Bourbon (100 proof if you have it)
- 1 oz (30ml) Fresh Lemon Juice
- 1 tsp Simple Syrup (optional, to taste)
- 1 Egg White (optional, for texture)
- Lemon twist and cherry, for garnish
Step-by-Step Instructions
- Dry shake (if using egg white): Combine everything without ice and shake 10 seconds to build foam.
- Wet shake: Add ice and shake hard 12–15 seconds until well chilled.
- Strain over fresh ice: Strain into an old-fashioned glass filled with fresh ice.
- Garnish: Express a lemon twist over the top, then add it with a cherry.
The History Behind the Recipe
The Amaretto Sour rode the 1970s liqueur wave as a simple two-ingredient pour (amaretto plus sweet-and-sour mix) and earned a reputation for cloying sweetness. In 2012, Portland bartender Jeff Morgenthaler published his rebuilt spec — more lemon, cask-proof bourbon, egg white — and single-handedly rehabilitated the drink for modern bars.
Presentation and Visual Appeal
Amber-gold over a large cube, with a pale foam cap if you include egg white. The lemon oils expressed over the foam add aroma that hits before the first sip — garnish where the nose meets the glass.
Pro Tips and Variations
If it still reads too sweet, add lemon in 1/4 oz increments rather than cutting syrup — acid corrects better than subtraction. A split base of rye instead of bourbon makes a spicier, drier version. Skip the egg white if you prefer; the drink is complete without it, just less silky.
This cocktail embodies the essence of classic mixology – simple ingredients combined with expert technique to create something truly extraordinary.
Frequently Asked Questions
Why is my Amaretto Sour too sweet?
Old specs used sour mix and no balancing spirit. Use fresh lemon (a full ounce), add the bourbon, and taste before adding any syrup — most palates need none.
Which amaretto should I buy?
Disaronno is the benchmark: rich, cherry-almond, consistent. Lazzaroni is drier and more bitter-almond — excellent if you find Disaronno too sweet.
Is the egg white safe and worth it?
With fresh eggs and a hard shake, yes — the alcohol and acid further reduce risk, and the texture payoff is real. Aquafaba (3/4 oz) foams nearly as well for a vegan version.
