Blood Orange Sour: Squeeze Me Sour

Jump to Recipe Print Recipe

If you’re looking for a cocktail that’s fresh, citrusy, and just a little bit silky, this blood orange sour needs to be on your list. It’s simple, beautiful, and bright.

This sipper has gin as the base, bringing those subtle botanical notes that pair so well with citrus. It’s layered with freshly squeezed blood orange juice, a splash of lemon juice for just a little tartness, rosemary simple syrup to round things out, adding a soft herby sweetness that plays so nicely with the gin, and an egg white for that silky, frothy top.

Whenever blood oranges are in season, and I spot them at the supermarket, I’m grabbing them. No question. They’re the cool ones of the citrus world, in my opinion. Like Fonzi cool. (Yes, I’m dating myself.) But every single time I slice one open, I still have that same reaction… wow, that’s kind of gorgeous.

March is actually your moment here. Blood oranges are still in season, but not for long, so if you see them, grab them. If you’re planning to squeeze these for cocktails and have friends coming over, do yourself a favor and grab extra. They don’t give you quite as much juice as a regular orange, and they go fast.

I was recipe testing them on friends, and they were such a hit, I completely ran out of juice and had to pivot to my backup signature sip… a cosmo. Not exactly a tragedy, but still. Lesson learned.

That said, they’re not always easy to find. If you can’t get your hands on blood oranges, you can absolutely swap in regular oranges or whatever citrus looks best at the store that day. Just don’t go all in on lemon or lime. We want a little tartness from them, not the whole show.

Time to squeeze out the details… here’s what you’ll need.

Blood Orange Sour Ingredients

Gin – I prefer Hendrick’s for its soft botanical vibe, but if you’re not a gin fan, you can easily swap in vodka or even tequila for a different twist.
Blood Orange Juice – Freshly squeezed is key here. Blood oranges aren’t always easy to come by, so any orange will work… just technically not a blood orange sour at that point. The color will shift too, but still delicious.
Lemon Juice – Just a little, freshly squeezed to brighten everything up and keep the sweetness in check.
Rosemary Simple Syrup – I’ll show you how easy this is to make. It adds a subtle herby sweetness that gives the cocktail a little extra depth. That said, plain simple syrup works just fine too.
Egg White – This is what gives you that frothy top and silky texture. If egg whites aren’t your thing, you can use a cocktail foamer (like this one on Amazon). It will still froth, just won’t have quite the same smooth finish.

How to make a blood orange sour

Start by squeezing those blood oranges. Strain through a fine mesh strainer into a cocktail glass to catch any pulp and keep things smooth. You’ll probably want to do this ahead of time, especially if you’re making these for a group. For reference, one blood orange will give you about enough juice for one to two cocktails… so plan accordingly.

Fill a cocktail shaker with ice, then add the blood orange juice, gin, rosemary simple syrup, lemon juice, and egg white.

Give it a good shake for about 10 seconds, until everything is well chilled and that frothy top starts to build. Strain into a cocktail glass.

Garnish with a small wedge of blood orange, or a dehydrated slice if you’re a planner and have those ready to go. I obviously did not plan that far ahead for this shoot… but next time, I will. Because this is absolutely a cocktail I’ll be making again and again.

About the Rosemary Simple Syrup

So this isn’t a deal breaker for this cocktail… but also, it kind of is.

It’s so simple to make. Literally toss about 2 sprigs of rosemary into a saucepan with equal parts sugar and water (1 cup each), bring it to a gentle simmer until the sugar dissolves, then let it steep and cool. That’s it. You’ve got yourself a really beautiful, herby simple syrup.

It adds just enough depth to make people wonder what that little something is in your cocktail. You can store it in the fridge for up to two weeks, so it’s worth making a batch and keeping it on hand.

ALL Your Blood Orange Sour FAQ’s

What is a sour cocktail?

A sour cocktail is all about balance: spirit, fresh citrus, and just enough sweetness to keep things bright, smooth, and easy to sip.

When are blood oranges in season?

Blood oranges are typically in season from December through March, with March being your last good chance to grab them. If you see them, don’t think twice, throw them in your cart. They’re not around for long.

Is it safe to put an egg white in your cocktail?

Yes, it’s generally safe to use fresh egg whites in cocktails. If you’re concerned, you can use pasteurized egg whites or a cocktail foamer as an alternative. The egg white doesn’t add flavor, it just gives that smooth texture and frothy top.

Can I use bottled blood orange juice?

You can, but fresh is always best. Freshly squeezed blood orange juice gives you a brighter flavor.
