In a small saucepan, bring 2 cups water to a boil. Add butterfly-pea flowers or tea bags and steep for 5–8 minutes until a deep blue color develops. Strain and discard the flowers or remove tea bags.

Stir in 1/4 cup sugar while the tea is still hot, mixing until dissolved.

In another saucepan, combine agar-agar powder with 1/2 cup cold water. Stir well, then bring to a gentle boil, whisking constantly for 2–3 minutes until agar fully dissolves. The mixture should be clear and thickened slightly.

Pour the hot butterfly-pea tea into the agar mixture. Stir to combine. Taste and adjust sweetness if needed.

Pour the blue jelly mixture evenly into 4 clear serving cups or glasses. Let cool to room temperature, then chill in the refrigerator until fully set, about 1–2 hours.

Just before serving, drizzle 1/2 tablespoon lemon juice over each jelly cup. Watch as the color shifts from blue to purple! Garnish with lemon zest if desired and a drizzle of honey or extra sugar for added sweetness.
