Elderflower Gin Sour Cocktail Recipe

I keep coming back to this drink because it marries floral elderflower with the crisp bite of gin and the creamy feel of egg white. There’s this balance: tart lemon, gentle sweetness, and that frothy top—it feels refreshing and, yeah, a bit elegant.

Equipment

• Cocktail shaker – A tight seal is key, especially when shaking with egg whites or aquafaba.
• Jigger – I like to measure each liquid so nothing overpowers.
• Strainer – Fine mesh gets rid of those pesky ice shards.
• Citrus juicer – Seriously, fresh lemon juice makes a world of difference.
• Bar spoon – Sometimes I give things a quick stir before shaking.
• Coupe glass – That foam deserves to be shown off, and this glass just feels right.

Having the right tools makes it all smoother. I mean, using a coupe glass? It just gives the drink that classic gin sour vibe.

Ingredients

• 2 oz gin (London Dry or elderflower-infused—dealer’s choice)
• 0.5 oz elderflower liqueur (St. Germain is my pick)
• 0.25 oz elderflower syrup (totally optional, if you want it sweeter)
• 0.75 oz fresh lemon juice
• 0.5 oz simple syrup (taste and tweak as you go)
• 1 egg white or 1 oz aquafaba (for the foam, obviously)
• Ice cubes

I usually reach for St. Germain because it’s got that smooth elderflower vibe. If I want an extra floral kick, I’ll add the syrup. Fresh lemon keeps things lively—no one wants a flat-tasting drink. And for that creamy texture, egg white or aquafaba does the trick.

Instructions

• Toss the gin, elderflower liqueur, lemon juice, simple syrup, and egg white (or aquafaba) into a shaker.
• Give it a good shake without ice (dry shake) for about 15 seconds—this is where the foam magic happens.
• Now, add ice and shake again until it’s nice and cold.
• Strain everything through a fine mesh strainer into a chilled coupe glass.
• Let the foam settle for a second before you serve.

I always dry shake first—it really helps with that froth. Then, shaking with ice chills it down and smooths things out. That double shake? It’s honestly the secret to a silky, foamy finish.

Notes

If I’m in the mood for more juniper, I’ll go for a London Dry gin. Want it even more floral? Elderflower-infused gin is the way to go. Sometimes I skip the egg and use aquafaba—works great if you want a lighter option.

You can play with the sweetness by adjusting the simple syrup and elderflower syrup. I go slow with the syrup; too much and you lose the gin.

Serving it in a coupe glass really shows off that foamy top. And if you chill the glass first, your cocktail stays cold longer—which, honestly, just makes the whole thing better.

Tasting Notes

The first sip? It’s bright and seriously refreshing. That gin gives a crisp backbone, and then the elderflower steps in with this gentle floral sweetness that somehow balances out the tartness of the lemon.

There’s a smooth, light texture—almost silky. If you use egg white or aquafaba and give it a good shake, you get this soft little froth on top. That creamy layer just makes the whole thing feel more rounded, honestly.

As the drink lingers, I start to notice these subtle layers. The citrus hangs around, sharp but never overwhelming the floral side. Elderflower keeps the finish a bit sweet, but not in a heavy or sticky way.

Whenever I throw on some edible flowers or a couple rose petals as garnish, the aroma shifts. Suddenly, it’s more delicate, and I can’t help but appreciate how the garnish makes it look as good as it tastes.

For me, the balance is key—sweetness, sourness, floral notes, all in check. If you go overboard with the lemon, the elderflower kind of disappears, but too much syrup and it’s just too sweet.
