Carmine is made from cochineal and is used to prepare Best's carmine
solution as a method for glycogen, perhaps not so commonly used these days.
Saffron (dissolved in wine?) was, of course, used by Leeuwenhoek in 1714 to
stain muscle.

"Cochineal and saffron spring to mind (more food-dyes than foodstuffs)"

Do tell Bill, what is cochineal used to stain in histology?
