M&S has one, Aldi is set to get one, and Sharish, and Ink Gin already are them. Colour changing gins.
It starts off blue, you add tonic, and it suddenly becomes pink. Oh, and it’s a G&T, I mean what’s not to like?
And now, you can get it in a dropper bottle to add to your own gin at home.
So let’s start at the beginning. What is it?
The blue colour comes from a flower – the Butterfly Pea flower. It also has another name, which if you understand female anatomy make make you snigger into your G&T a bit. It’s the Clitoria Ternatea. I’ll give you a moment.
Done? Good. The flower is native to Thailand and is often used in teas because the blue colour indicates a high level of antioxidants, and in some recipes to colour rice. So, it’s kind of good for you. Of course, in order to change the colour, you’re going to add a form of acid (the citrus in your tonic water) so what that’s going to do to the antioxidants, I’m not sure. I’ll ask a chemist and get back to you.
Back to the acidity. Do you remember litmus papers from school? You’d test something to see if it was acid of alkaline using the paper. Blue for alkaline, pink/red for acid. If it’s neutral, it doesn’t change.
B’Lure offers reacts in the same way. The concentrate is blue, you add acid, it goes pink.
So from this:
The higher the acid, the more pink it goes, much like litmus paper does. So if you have a G&T and add lime along with your tonic, you can expect a stronger pink, rather than a purple.
If you also want to show off a little, add it to ice cubes, and as they melt, they’ll gently colour the drink, reacting with the acid over time to give you a blend of blue/purple and pink to your drink.
Whilst I’m not sure practically how much I’m going to play with it, I can’t help thinking that I should do something with it, something a little playful, maybe using a bake.
I’ll update you!
