Looks like honeycomb and is edible, but it is something different.

GHEVRA IS A Rajasthani food preparation containing ghee, maida (refined flour), milk, and sugar syrup. This mixture is poured into a (usually) circular metal mould and heated vigprously until it attains a texture like honeycomb. Various sweet toppings can be put on the finished Ghevra. We sampled a piece topped with rabri (a sweet made by boiling down milk slowly).
