Blue herbal tea that is becoming more and more popular in Japan. It is mainly extracted from herbs such as "butterfly pea" and "mallow blue", and when acidic substances are added, the blue pigment reacts and the color changes. This time, I took advantage of this property and enjoyed the "hydrangea-style drink" that is perfect for this season.

I used "Hawaiian Blue Tea" that you can buy at KALDI Coffee Farm. In addition to butterfly pea, lemongrass and Hawaiian herb "Mamaki" are blended, and it is recommended for those who drink for the first time with a lemon-like scent and a taste that is not peculiar.


First, pour a thickly extracted herbal tea into a glass of ice and add soda with lemon juice.



Then, the color changes from the soba you put in to purple! You will be fascinated by the delicate changes like at dusk.



In search of more transparency and beauty, I arrived at "Plum Hanip," which can also be purchased at KALDI. A transparent juice made by adding honey to plum juice extracted with sugar.


Now put the plum honey in a glass of ice first and then gently pour herbal tea. Now the juice, purple and blue gradations are complete! The sweetness is moderately diluted and you can drink very much.




Of course, you can enjoy the same change with drinks other than those introduced, or by squeezing lemon juice directly. It's like a science experiment and you won't get bored no matter how many times you do it, so please try it even when you can't go out due to rain!
