1. The butterfly pea flowers are soaked in heated water for about 8 hours. The longer the time, the darker the color, and the more flowers and darker.
2. This is the color after 8 hours of soaking. I don't know why it turned red under the light. It should have been blue.
3. Peel 6 grapes and 2 lemon ice cubes.
4. Put grapes in the high glass first.
5. Add one-third cup of cold white boil.
6. Add lemon ice cubes.
7. Finally, pour the butterfly pea flower water, and drink a cup of ice-cold sweet and sour butterfly pea flower grape lemon.
Tips:1. The more butterfly pea flowers or the longer the soaking time, the darker the color, and the color will be leached easily by soaking in hot water.
2. The lemon ice cubes are made in advance. You can see the previous recipe. The simple one is to chop the lemon into pieces, add honey and boil and mix well, then put it in an ice tray and freeze it into ice cubes.
3. The grapes can be replaced with other fruits, and the cold boiled ones can also be replaced with other beverages.
