I am trying to make sweet sushis that look like standard (savory) ones. Most of them I can make easily (using black-coloured pancakes as nori sheets, grapefruit as salmon, kiwis as avocado, and s.o.).
But I am stuck when I try to simulate a slice of salmon around the rice. Something like that
I read a hint from a (french) recipe : using a mixture of gelatin and fruits purée, spread over a silicon sheet. Unfortunately, I have tried it many ways, but kept encountering the same pb : it's sticky and nearly impossible to remove from the silicon without tearing it miserably.
My question is not about how to simulate the salmon slice (I will find other ideas), but about how I can (or IF I can!) make such a gelatin-based slice that I can easily remove from the silicon (or whatever tool you may suggest)
