Dr. Jekyll and Mr Hyde transforming potion | Strange Case of Dr Jekyll and Mr Hyde

Wonder what makes this Dr Jekyll and Mr Hyde transforming potion special?

There’s two reasons.

  1. While butterfly pea flower extract makes the liquid blue, all the other liquids we’re adding are clear. And yet the colour changes.
  2. Normally when you add other colour liquids together, they typically they become darker. But this drink becomes lighter, from dark blue to light pink-purple.

Butterfly pea flower extract is special because it reacts with the ph level of the liquid. So what makes the drink react is the citric acid and the lime juice.
Yes, you could bypass the salt and citric acid, but in Dr Jekyll and Mr Hyde, ‘the particular salt’, is one of the ingredients that gives the potion the reaction it does. While we didn’t add the blood red liquor, this is one element we wanted to keep it authentic.

“I found what seemed to me a simple crystalline salt of a white colour. The phial, to which I next turned my attention, might have been about half-full of a blood-red liquor, which was highly pungent to the sense of smell, and seemed to me to contain phosphorus and some volatile ether. At the other ingredients I could make no guess.”

-Strange Case of Dr Jekyll and Mr Hyde, Robert Louis Stevenson
