Let's make the jelly
Add lemon juice to water
Add sugar
Transfer to a pot and heat until sugar dissolves
Prepare gelatine sheets. In a bowl of ice water, add in sheets one by one ensuring they are fully submerged before adding another (prevent sticking to each other)
Squeeze excess water out of softened gelatine, and add into the hot lemon juice mixture
Strain mixture into a bowl
Mix in a tiny amount of blue food colour (until desired intensity)
Set aside to cool completely
Let's make the ganache
In a microwave safe bowl, pour in heavy cream. Microwave at 30 sec intervals until it becomes very hot
Add in chocolate (ensure it is fully submerged in the hot cream)
Let sit for 1-2 min (before mixing)
Let chill in fridge for 30 min or until it is a thick but spreadable consistency (eg nutella)
Let's make the sand and mountain greenery
In a bag, crush digestive biscuits until it resembles fine crumbs
Separate 2/3 of it into a bowl
Here I added green GEL food colouring (please take note the biscuits won't turn green with gel colour hehe)
Add liquid green food colour and mix till desire intensity
Ganache should be this consistency

Layer cake with ganache evenly
Please chill in fridge for 15-20 min if you have the time (I didn't which made shaping the island a bit harder)
Carve cake into desired island shape. Note: uncarved parts will become your mountains
Cover entire cake with the soft ganache (if your ganache is very hard it will be difficult to cover; let it sit at room temp)
Chill in fridge for 15-20 min or until ganache firms up
With the leftover cake, crumble then add ganache bit by bit until it forms a 'dough'
Make mountains with the cake 'dough'. Shape and press it to ensure it is firm and sticks to the cake
Cover the mountains in ganache
Chill in fridge for another 15-20 mins or until ganache hardens
Meanwhile, melt some white chocolate
I do not have a cake mold with removable base so here is how I did it with a normal cake pan
Spray some water onto the insides of the pan so that the cling wrap will stick well
Insert the acetate sheet and tape the ends together
Pull and wrap the clingwrap tightly around the acetate sheet
Take the cling wrap and acetate sheet out carefully, and tape ALL AROUND to secure the wrap onto the acetate.
If there are any air bubbles, pin it down with more tape to ensure that the jelly does not leak
Put it back into the cake pan
With a spatula, 'paint' corals all over the island (parts that will be submerged later) with the melted white chocolate
Let chill again for 10-15 min for the chocolate to set
Once chilled, drop the cake into the cake pan gently
Fill with COOLED jelly mixture (HALFWAY)
If you fill it up all the way with the jelly mixture, the cake will float (so fill it up to halfway)
Let it set in the fridge for 1-1.5 hours
Once set, fill it up to desired height with the remaining jelly mixture (there will be leftover jelly)
Let it set in the fridge for a few hours (Best overnight)
Carefully remove from pan, cling wrap and acetate sheet
Peel gently
Paint the mountains with white food colour to create a rocky feel
Cover the jelly cake with cling wrap before sticking on the crushed biscuits to make the greenery (slipped my mind lol)
Gently press and stick the green crumbs onto the mountains
Carefully remove the cling wrap
If there are any crumbs that fell onto the jelly part, wipe gently with a damp kitchen towel
Make waves by painting with the white food colour
Add the plain biscuit crumbs to act as sand
I added Thousand Sunny (comment down below if you want a tutorial!)
