Ocean cake - what icing won't melt with jelly?

[wallpeppering]

Planning a birthday cake in the style of an "island cake", but I want the mountain to be ice-like. The cake will be chocolate, and I'm looking for a white frosting/icing that will take the jelly without melting. It cannot be white chocolate because that's a little yellow! Any recommendations?

Island cake looks like this:

The instructions for that glorious cake above say "Painted the cake with white gel coloring mixed with Vodka.You can use lemon extract instead"

What white gel colouring would that be? I want the entire area to be white and worry that gel colouring might taste a bit awful...

Alright then, no ocean cake fans here! What I have decided to do is use white chocolate with the addition of some Wilton White to hopefully take some of the yellow away + blue jello for the sea. It's going to be an arctic cake, will post an update if it goes well.

Sounds amazing
I'm not artistic enough for things like this but perhaps if you look on Facebook you'll find a group dedicated to it?

That’s a good idea cultkid , thank you!

I just had a look a lot of people have posted on fb after making them xx

I'd use white chocolate ganache for a lightish base and then go over it with blue and white to reduce the yellowness. Perhaps using the squires coloured cocoa butter in the cool colour set?

Thanks for the comments, sorry I didn’t see them on time! So mixing the white chocolate with the white food colour was a total disaster, as the chocolate turned into a kind of sandy sludge! Luckily I had some more white chocolate and I accepted that it was never going to be ice-white. After the white colour disaster I played it safe by sticking with “just” the icy scene...but my girl was very happy with her cake and luckily did it know about the ocean plans either.

I would say that instead of the white chocolate (that went after a layer of chocolate buttercream that I left overnight in the fridge) I could have used just buttercream for the snow. While chocolate makes everything ever so sweet!
