To form the replicas, an actual piece of food is meticulously measured from every angle, then embedded in silicon to get all the surface details (plastic artists even do this for something as seemingly simple as rice), and the resulting mold is filled with molten plastic. Once it's heated, the basic shapes and colors are in place, at which point artists painstakingly carve and paint the plastic by hand. They amp up the color a bit to make it even more enticing than the real thing. When it’s finished, the artist will cover it in an adhesive for its glossy finish, and voila! Plastic food that looks good enough to eat.
