Blackberry Lavender Gin Sour

Last Updated on June 13, 2023 by Leah Hall

This blackberry syrup cocktail is a great summer sipper with added lavender. We love a great egg white cocktail!


We recently received some great new glasses from JoyJolt that were quite stunning. We knew we had to do something pretty spectacular to show off the beautiful glassware. We thought right away of an egg white cocktail, because egg white foam shows off glassware really well, and with the color found in the stems of the these glasses, we knew it would be great to have a color that complimented it, as well!

The glasses we received were the Black Swan Martini Glasses, with a beautiful purple hued stem and glass bottom, with a gradient from purple to clear. These glasses have a beautiful sweeping bowl and tall stem, that makes them striking! This purple was the inspiration for this blackberry lavender flavor!

We started out with some lavender honey simple syrup, the honey giving a deeper flavor, and the lavender adding some great herbal aspects. Also, we know from other cocktails that lavender and blackberry go really well together, so we knew it would be a winner in the same drink.


How To Muddle Blackberries

We muddled the blackberries with the simple syrup to incorporate the flavors and break down the berries. This helps add flavor to the drink, and to separate the seeds from the berry pulp and juice. It’s easiest to muddle in the bottom of the shaker and then double strain when you mix the cocktail to make sure the seeds stay out.

Egg White Cocktail

We then added the egg white to the mix along with a bit of lemon juice. The combination of lemon juice and alcohol helps to unravel the proteins in the egg to make a wonderful thick foam when shaken. When strained through a fine mesh strainer into a glass, the foam becomes velvety smooth and pillowy and the perfect topping to a cocktail! The lemon juice also makes this drink into the classic sour style cocktail!

To top this cocktail, we added some sage bitters, and some edible flowers we got from a local farm here in Omaha! The sage bitters bring a refreshing hint of evergreen perfume to the drink that pairs up well with the gin and the fruitiness of the blackberries. Add in the floral hints from the edible flowers and the whole thing comes together in a beautiful combination of visual and culinary delights!

We think it totally shows off the beautiful purple color of the Black Swan glasses from JoyJolt, and we added the pretty color flowers for more elegance. Such a great one, and we hope you make it soon!

I tried this and it's delicious! The only thing I would change next time is muddle the berries with the gin, strain it into a new shaker, add the syrup, juice and egg whites and then shake and strain into the glass. I found that when I strained everything together with the muddled berries, I ended up having little only a little of the froth left in the actual drink.

Hi there, sorry you didn't get much foam. Egg white cocktails can be fickle. That's why the dry shake/wet shake method should do well to make you foam. You could also try it as a wet shake (with ice) and then dry shake (take out the ice) and shake again. I would also say shake for at least 30 seconds to activate those egg whites! Hope you try it again, cheers!

This just might be the prettiest cocktail I've ever seen. I love the floral arrangement you've got going on there! This would be perfect for a brunch or wedding shower. I'm going to throw this idea out there to my ladyfriends when we start talking about our friends wedding shower :) Can't beat berries and floral notes, either!

This is such a gorgeous drink! I love lavender, but it can sometimes be overpowering when not balanced out with another primary flavor. I love that this has blackberry also because I think those two flavors work so beautifully together. I can't wait to try this recipe!
