Last year, in Poland, I fell in love with the local lemonade recipe: a mildly fermented soda using beautiful blue cornflower petals and sugar that turns into a bright pink fizzy drink.
It isnt something we do here in the UK, at least that I have never come across. Polish ethnobotanist, Łukasz Łuczaj @thewildfood said he has only seen it in Poland, and kindly agreed to translate his video into an English version so that you can learn how to do it here too.
