Prepare to be spooked by the Purple People Eater Halloween cocktail! Featuring a natural ingredient with magical color changing properties. Make this Halloween drink EVEN SPOOKIER with some edible fake blood around the rim of the glass…
I have been sitting on this cocktail for several weeks debating whether or not to post the recipe. If I am being completely honest, part of the reason for this procrastination is that I didn’t know what to name it. It looks straight out of Monsters Inc. to me, but that’s not very scary now, is it…
Then, just I was about to throw in the towel, my friend Julia jumped in with the perfect name ‘One Eyed One Horned Flying Purple People Eater’!!
This is actually the title of a very catchy song – just Google it and prepare to dance around with your kids (or dogs) for a little bit 😉
PURPLE PEOPLE EATER HALLOWEEN COCKTAIL
This Halloween drink is basically a riff on the Red Queen which is, by far, the most popular cocktail on my blog.
A mix of cranberry juice, lemon juice, gin and St Germain elderflower liqueur it’s a perfect cocktail to toast during the festive season.
But give it a little twist with the magical color changing ice (actually Butterfly Pea Flower Tea) and it is perfect Halloween fodder.
I was introduced to the properties of blue pea flowers by the Flavor Blender and these days you can easily buy them on Amazon.
The flowers produce an intense blue tea and can also be used to turn vodka, gin or tequila a vibrant blue/purple color.
But what’s even more amazing is that the blue colour will turn to purple when mixed with acidic liquids like lemon juice.
You can have endless fun playing around with this – I actually made a series of other cocktails that I might share some other time.
So here’s to a thoroughly spooky Halloween – just beware of Purple People Eaters, they are actually quite potent!

It says add lemon juice but there isn’t any under the ingredients. How much are you supposed to add?
hiya – you can add one tablespoon and adjust to your taste
Love it – would a kids version work with lemonade instead of the booze? My kids would be desperate to try these if they saw me making them!
Yes! You could use lemonade and elderflower cordial 🙂
So cool! Love this cocktail Lucy. So clever x
