Butterfly pea tea indicator solutions

Butterfly pea tea

Another variation on the cabbage-water-indicator we've tried out lately - butterfly pea tea.

You can buy it from Amazon, but not from any specialist tea shops. When I phoned them up and asked them about it, the Oxford ones were curious, and had never heard of it!

It's almost flavourless, so works well in cocktails, and a few leaves make a vivid, bright blue liquid. Squeeze some lemon in, and it turns vibrantly pink (less effective with dry ice - just turns purple. Needs more push).
You can add gin to it safely without changing the colour, although shockingly most people don't want to drink a cocktail that tastes mostly of gin. Elderflower cordial is a good add that doesn't affect colour.
