Take the jelly mould from the fridge, and gently scratch the jelly with a sharp knife. This will make the jellies stick together. Then pour the hot liquid on top. Gently place the sakura blossoms into the mould ( dip and gently shake the flower into the jelly liquid, so that the flower will open up nicely as shown in the picture) .
Leave jelly to cool in room temperature and chill it in the fridge for 2 hours before serving.
