Osmanthus cake

Gently rinse the dried osmanthus flowers and soak them in 50 grams of warm water for 10 minutes to soften and release their aroma. Drain the dried osmanthus flowers, reserving the fragrant water.

In a medium saucepan, combine the remaining 650 grams of water and the agar-agar powder. Whisk thoroughly to ensure the agar-agar powder is well dispersed.

Bring the mixture to a boil over medium heat, stirring constantly, until the agar-agar powder is completely dissolved. This typically takes 2-3 minutes after boiling begins.
