Why You Will Love This Recipe

Floral cocktails are a great way to celebrate earthy flavors in a drink! A delightful cocktail that incorporates floral and citrusy flavors, making it a refreshing and visually appealing drink. And this makes it perfect for spring and Easter!

A sour cocktail is traditionally made with a liquor, lemon juice, something sweet, and an egg white.

But if you do not want to use an egg white, you can skip it!

This gin sour recipe highlights floral flavors through lavender and elderflower paired up with lemon. It is an alcoholic drink variation of our Lavender Field Mocktail.


Gin – a great support liquor for the herbal and floral notes of the cocktail

Elderflower Liquor – slightly floral and rather sweet

Lavender Simple Syrup – this is where we get the lavender flavor from

Lemon Juice – fresh is best. Balances out the sweetness

Egg White – optional. This is a traditional ingredient in a sour cocktail and will give more of a silky texture and foam.

Modifications and Substitutions

You can vary the recipe by using different types of gin or swap it out for vodka. Some gins have more botanical or floral notes, which can enhance the cocktail’s flavor. I personally find Hendrick’s to be very floral compared to a London dry style which is heavier on the juniper side.

Adjust the sweetness to your liking by adding more or less simple syrup.

If you want a bit of fizz, you can top the cocktail with a splash of soda water or sparkling wine for a “sparkling Flower Power Sour.”
