Classic amaretto sours get a bad reputation because they are usually made with sour mix: a shortcut that adds too much sugar and none of the brightness you want. A better amaretto sour recipe starts with fresh lemon juice, a small measure of bourbon, and rich simple syrup you can dial in to your taste. With an egg-white dry shake, this version comes out balanced, creamy, and foamy — the way a good bar version should.
Ingredients
Yield: 1 cocktail Glass: old-fashioned or rocks glass Equipment: cocktail shaker, jigger, citrus juicer, fine strainer
- 1½ oz amaretto
- ¾ oz bourbon
- ¾ oz fresh lemon juice
- ¼ oz rich simple syrup (2:1), plus more if needed
- 1 large egg white (or 1 oz aquafaba)
- Garnish: lemon peel
Rich simple syrup is just two parts sugar dissolved into one part water. It adds sweetness without as much water as standard simple syrup, so it keeps the cocktail full-bodied.
How to make it
- Combine the amaretto, bourbon, fresh lemon juice, rich simple syrup, and egg white in a cocktail shaker with no ice.
- Seal the shaker and dry shake hard for 10 to 12 seconds. This step builds the foam; do not skip it.
- Add a handful of ice and shake again until well chilled, about 12 to 15 seconds.
- Strain into an old-fashioned glass over a large ice cube or fresh rocks ice.
- Express a lemon peel over the drink, drop it in, and serve.
If you prefer a reverse dry shake, shake all the ingredients with ice first, strain off the ice, then shake a few seconds without ice. Both methods work; the important thing is to give the egg white a chance to aerate before the drink is over-diluted.
Why the bourbon matters
The bourbon is small — ¾ ounce — but it changes the drink. It adds oak and spice and takes the edge off the amaretto’s sweetness so the cocktail finishes dry instead of cloying. If you use a different amaretto, taste your drink before adding extra syrup; some brands are sweeter than others.
Mistakes to avoid
- Do not use sour mix. It makes the drink taste artificial and one-note.
- Do not skip the dry shake. The dry shake is what creates that smooth foam on top.
- Do not load up on simple syrup. The lemon should make the drink taste bright, not mouth-puckering. Start small and add a few drops only if needed.
- Do not add ice before the dry shake if you are using the standard method; the whole point is to build foam before dilution. If you want a colder shake, use the reverse method above.
Raspberry amaretto sour variation
For a raspberry amaretto sour, gently muddle 5 or 6 fresh raspberries in the bottom of the shaker before adding the liquids. Use the same recipe, but reduce the rich simple syrup to 1/8 ounce or leave it out if your amaretto is already sweet. After the shakes, double-strain through a fine strainer into the glass to remove the seeds. The raspberries add a little tart fruit flavor and a pale red tint without becoming dessert-like.
Small adjustments
- More foam: Add another egg white or use slightly more aquafaba, and dry shake a few extra seconds.
- More structure: Rye whiskey works in place of bourbon if you want more spice.
- No egg: Omit the egg white for a simpler sour, or use 1 oz aquafaba to keep the foam vegan.
Raw egg whites are a common cocktail ingredient, but they are not for everyone. If you are serving someone with a weakened immune system or would rather avoid raw eggs, use pasteurized egg white or aquafaba. Check official food-safety guidance if you are unsure.
Why this recipe is better than a sour-mix version
Sour mix is sweet, mostly acidic, and flavorless. By controlling the sweet and sour yourself, you get a cocktail that tastes like the amaretto, with a clear lemon aroma and a soft layer of foam on top. The bourbon makes it closer in spirit to a modern bar amaretto sour: still nutty and sweet, but rounded and not cloying.
The recipe is also easy to remember. One and a half amaretto. Three-quarters bourbon. Three-quarters lemon. A quarter-ounce of rich syrup. One egg white. Shake cold and serve.
FAQ
Can I use bottled lemon juice? Fresh lemon makes a noticeably better drink. Bottled lemon juice can work in a pinch, but the balance may change.
What if I don’t have rich simple syrup? Use ½ oz standard simple syrup (1:1) and taste. You can always add a little more if the drink is too tart.
What is the best amaretto? Choose one you like on its own. A good amaretto will make a better cocktail, and the brand you prefer will shape the final drink.
Can I make a batch of this amaretto sour recipe? You can scale the measurements, but leave out the egg white until each drink is made, and shake each cocktail individually so the foam stays silky.
