Yes, you’re still in the painting gallery. This super realistic oil on panel by Arnout van Albada is part of a series of 2013 paintings featuring puddings and jelly. They are exhibited at My Life in Art gallery in London and Galerie Mokum in Amsterdam (which is great cause it means you can buy them provided you can afford it).
The Dutch artists achieves this realistic effect using a very specific technique that involves oil painting over a base monochrome layer of egg tempera, a mixture made from egg yolk, water, and pigments. It’s the overlap of the thin oil paint layers that give the impression of transparency and depth.
