This is purple perilla leaves. I boiled them about 10 min.
こちらが葉っぱを漉した後の液体。かなり濃い紫。
This is the liquid after straining all the leaves. Very dark purple.
そこにレモン汁を入れたら一瞬にして色が変わった。。あらま!
Adding lemon juice to the liquid quickly changed its color. Wow!
I got this beautiful colored drink in the end. Acidity of lemon juice changed the pH of the liquid and its color. You can read about it here => CLICK<=
