Amaretto sour drink recipe: how to make one that actually tastes good

An amaretto sour is a sweet-tart cocktail made with amaretto liqueur, fresh lemon juice, and (ideally) egg white, shaken until you get a silky foam on top. Done well, it hits the right balance between nutty sweetness and bright citrus. Done badly, it tastes like bottled sour mix and disappointment. This guide shows you exactly how to get it right, including when to bring in amaretto whiskey for an even better result.

What makes a great amaretto sour drink recipe?

A great amaretto sour drink recipe is built on three things: fresh juice, the right ratio, and a proper shake. No shortcuts.

Most bad versions of this cocktail come from two places: using store-bought sour mix instead of fresh lemon juice, and skipping the egg white. The egg white does not add flavour. What it does is create a creamy, cloud-like foam that lifts every sip and smooths out the acidity. Without it, you just have a sweet lemon drink. Zie voor de verdieping meer over amaretto sour.

Start with your amaretto. Quality matters here. Bols Amaretto Liqueur gives you a clean, full almond flavour without being cloying, which makes balancing the citrus much easier. If the liqueur itself is too artificially sweet, no amount of lemon will fix it.

The second key is freshness. Squeeze your lemons right before you shake. Lemon juice oxidises fast and loses its brightness within about 30 minutes. That fresh, slightly floral edge is what makes a sour actually sour in the best possible way. This is a small step that makes an outsized difference.

The classic amaretto sour recipes: ingredients and ratios

Here is the base recipe that works. These quantities make one drink.

Ingredients:

• 50ml amaretto liqueur
• 25ml fresh lemon juice
• 10ml simple syrup (optional, depending on your amaretto)
• 1 egg white (or 20ml aquafaba as a vegan swap)
• Ice for shaking
• Garnish: a lemon slice and two maraschino cherries

The 2:1 ratio of amaretto to lemon is a reliable starting point. Some amaretto sour recipes call for more lemon to cut through sweeter liqueurs. Taste your amaretto first and adjust accordingly. If it already leans sweet, hold back on the simple syrup or leave it out entirely. We gaan hier dieper op in bij onze uitleg over apricot brandy sour.

Simple syrup is there to soften the edge of very tart lemons, not to make the cocktail sweeter. Use it only if your citrus is especially sharp. One part sugar dissolved in one part warm water is all you need. Let it cool before using.

For the garnish, a maraschino cherry on a pick looks clean and classic. A thin lemon wheel or a piece of expressed lemon peel adds an aromatic note. Press the peel over the glass before you drop it in, releasing the citrus oil across the foam. Small detail, real impact.

How do you shake an amaretto sour properly?

Dry-shake first, then shake with ice. That is the technique.

Add all ingredients to a shaker without ice. Seal it and shake hard for about 15 seconds. This step emulsifies the egg white and builds the foam structure. Then add a generous handful of ice, seal again, and shake for another 10 to 15 seconds until the shaker is very cold. Double-strain through a Hawthorne strainer and a fine mesh strainer into a chilled rocks glass over a large ice cube. The fine mesh strainer catches any stray fragments of ice or lemon pulp that would otherwise break up the foam.

Pour slowly. Let the liquid settle under the foam, then gently spoon or pour the remaining foam on top if any stays in the strainer. The result should be a clean separation: cocktail below, white foam above. That foam is what professionals call mouthfeel, and it is what makes this drink feel luxurious rather than just sweet.

If you prefer not to use egg white, aquafaba (the liquid from a tin of chickpeas) works well. Use about 20ml. The foam is slightly less stable but still gives you a pleasant texture. Alternatively, some bartenders use a small amount of cream, though this changes the drink's character toward something richer and heavier.

amaretto and whiskey: the upgrade worth knowing

This is the version that takes the drink from pleasant to genuinely interesting.

The combination of amaretto and whiskey became popular after cocktail writer Jeffrey Morgenthaler published his take on the recipe around 2012. His insight was simple: amaretto on its own is sweet and one-dimensional, but adding a measure of bourbon introduces oak, vanilla, and a gentle heat that gives the cocktail structure. The result is not a new drink. It is the same drink, but with depth.

Use bourbon rather than Scotch for this variation. Bourbon's natural sweetness from corn works with the almond notes in the amaretto, while Scotch can clash if it has smoky or peaty characteristics. A 2:1 or 1:1 ratio of amaretto to bourbon both work, depending on how prominent you want the whiskey to be. At 1:1, the drink is drier and more complex. At 2:1, the amaretto stays in the lead.

This amaretto and whiskey drink also benefits from a small addition of Angostura bitters, two dashes stirred in before you shake. Bitters tie the sweet and sour together and add a subtle spice that rounds out the finish.

Amaretto whiskey drink variations to try at home

Once you understand the base recipe, small adjustments open up a lot of room to experiment.

One easy variation is to swap simple syrup for honey syrup (one part honey, one part warm water). It adds a floral sweetness that pairs well with the almond character of the amaretto. Another option is to use orange juice instead of lemon for a softer, less acidic version. The result is closer to a whiskey sour with amaretto, which is a great introduction for guests who find straight citrus too sharp.

If you enjoy exploring the wider world of classic sour cocktails, an amaretto sour sits naturally alongside an apricot brandy sour or a cherry sour. These follow the same structure: a base spirit or liqueur, fresh citrus, a sweetener, and optionally egg white. Mastering one teaches you the logic behind all of them. The technique transfers directly. Vergelijk dit met onze aanpak van vanilla sour.

For a lighter, more refreshing take, try the amaretto spritz. It uses prosecco to cut through the sweetness and is a great warm-weather alternative that does not require a shaker. Good to have in your repertoire when you want something quick and crowd-friendly.

Amaretto with whiskey: balance, ratios, and garnish

Getting amaretto with whiskey right comes down to understanding who leads and who supports.

The amaretto and whiskey drink works because both ingredients have complementary flavour profiles. Amaretto brings almond, marzipan, and a slight bitterness from the apricot kernel that most people do not notice consciously but do notice as balance. Bourbon brings vanilla, caramel, and a dry oakiness. Together, they form a cocktail that is sweet but not saccharine, strong but not aggressive. Fresh lemon pulls it all into focus.

A common mistake is using too much lemon in the whiskey version. With plain amaretto, 25ml works well. When you add bourbon, the alcohol content rises and the flavour becomes more assertive, so the citrus does not need to work as hard. Start with 20ml lemon juice and taste as you go. Balance is always about adjustment, not fixed formulas.

For garnish on the whiskey version, a fat orange twist expressed over the foam works better than the standard lemon and cherry combination. The orange oil picks up the vanilla notes in the bourbon and creates an aromatic bridge between the glass and the first sip. At Bols, we have spent decades studying how garnish affects perception, and the right aromatic over the foam changes the experience before you even taste it.

At the Bols Bartending Academy, techniques like this are part of what we teach when we talk about sensory layering. A cocktail is not finished when it is in the glass. It is finished when it is in the hand. Every detail between those two moments counts.

Frequently asked questions

Can I make an amaretto sour without egg white? Yes. Use 20ml of aquafaba (the liquid from canned chickpeas) as a direct swap. The foam is slightly less stable but still gives the cocktail a creamy texture. If you prefer to skip foam entirely, the drink still tastes good, just thinner in the mouth.

What is the difference between an amaretto sour and a whiskey sour? A whiskey sour uses whiskey as the base spirit with lemon juice and simple syrup. An amaretto sour replaces the whiskey with amaretto liqueur. The amaretto and whiskey variation combines both, giving you a drink that sits between the two classics, sweeter than a straight whiskey sour but drier and more complex than a plain amaretto sour.

Do I need simple syrup if my amaretto is already sweet? Not always. Taste your amaretto first. If it is already quite sweet, skip the syrup and use a little more lemon juice instead. The goal is balance, not a fixed ingredient list. Many good amaretto sour recipes leave the syrup out entirely when using a sweeter liqueur. We gaan hier dieper op in bij onze uitleg over bols sour apple liqueur.

Why do I dry-shake before adding ice? Dry shaking (shaking without ice first) emulsifies the egg white and builds the foam structure before the cold temperature sets everything. If you add ice immediately, the egg white does not get enough mechanical energy to form a stable foam. Dry shake for 15 seconds, then shake with ice for another 10 to 15 seconds.

What glass should I use for an amaretto sour? A rocks glass (also called an Old Fashioned glass) over a large ice cube is the most common serve. It keeps the drink cold without over-diluting it and gives the foam space to sit on top. A coupe glass is a stylish alternative if you prefer to serve it straight up without ice.
