Citrus, floral gin with a slightly sour finish.
The recipe above has been my preferred recipe for some years. However, in early 2020, I decided that...
I think the sky blue colour is essential. So maybe a little bit to much violets. Thinking about substituting it with Blue Curaçao. But then maybe loosing the complexity and the sport.
Last comment on this; speaking to a botanist friend of mine, the blue / purple is from Anthocyanins (pH sensitive) which are found in both Violets and Butterfly Pea Blossom.
I agree with Tracy. Bitter Truth results in a lovely pale blue colour even though it is more purplish in the bottle. I’m guessing there is some additive which is pH sensitive as I have noticed it lightens in the presence of lemon juice. (Pure speculation, but maybe butterfly pea blossom? This is what gives the Canadian gin Empress 1908 its indigo hue and which changes colour depending on the pH of other cocktail ingredients.)
