Interesting details! Thanks!
When I worked in advertising, we used to do all kinds of yucky stuff to make food products look good for the camera, like placing a lighted cigarette butt on the saucer behind the cup of cold coffee to make “steam” appear to be rising from a cup of hot coffee. We sprayed the outside of cold drink cups with plastic beads of “condensation” and used plastic “ice cubes” that wouldn’t melt in the studio lights. We rubbed brown steak sauce on cold roast turkeys to make the skin look nicely crisped and sprayed them with lacquer for shine, etc.
I read that photo or video “ice cream” is usually crisco or lard, because the ice cream would melt too fast to properly dress the scene before the photo or video could be taken. Food make-up is an art all to itself for advertising. That’s why when you get that carton of McDonald’s French Fries, it never looks as good as the photo on the menu. . . Or the Quarter Pounder with Cheese or Big Mac is never as thick and juicy as what they say they are selling you.
