Be careful when pouring boiling water to prevent splashing and burns.
Place 20 dried butterfly pea flowers into a glass measuring cup, pour in 500 ml of hot water, stir with a spoon, and let steep for about 5 minutes until it becomes a deep blue-purple tea extract; strain and set aside.
Watch out
Steep long enough so the liquid becomes very dark and concentrated, otherwise the color layers won't contrast clearly.
