Put tofu, green tea powder and 50ml of the milk into a blender, whiz until smooth! (The amount of milk is adjustable, if you need more liquid to have a smooth blend, feel free to put more milk in, just remember to put less in in the next step.)
Put the remaining milk (200ml), double cream and sugar into a saucepan, heat till tiny bubbles form round the side. Do NOT boil.
Soak gelatine leaves in COLD water for 5 mins, take them out and squeeze all the water out of them.
Combine 1/3 of the hot milk mixture to the green tea mixture in a bowl. Stir and mix well.
Dissolve the gelatine leaves in the remaining 2/3 of the hot mixture.
Pour all the hot mixture into the green tea mixture, mix well and put it in the fridge.
Let it rest for 15 minutes, take it out and give it a stir. Now pour into your chosen jelly bowls! (I love my new Tala jelly bowls as they have lids on both sides, so it is impossible to have a disaster when you turn the jelly out!)
