>>7996804the image was part of the promo material for a new Nordic-inspired food and drinks menu being introduced on Scandinavian Airlines (SAS) about 5-6 years ago; from what info I could find about the menu, aside from various locally sourced high quality meat, vegetable, and fruit options, the menu was supposedly also going to include some exclusive handmade artisan chocolates
so the best guess I can come up with is that the blue cube might be an example of one of those handmade chocolates, that's either been wrapped in a blue foil, or painted with a blue food coloring, to represent the SAS airline colours
to be honest, looking at that image, the menu looks like it was probably pretty damned good for being airline food
