This is a Bevelled Slab - but here the Bevel is actually the majority of the sculpt! The rest of the Slab just forms the flat floor of the tray.
Again I made the curves in Inkscape, and imported to make my model in Curvy. The render is also Curvy (But using Post-Processing rather than raytracing for the reflection!)
And some contents for the tray. This time Macaroni curves drawn directly in Curvy. The pasta was dropped to the surface of a sphere to make the heap shape. The sauce was a flat mesh Dropped onto the pasta to mimic it's overall shape and then tweaked so the pasta shows through in places.
