Australian food history blogger The Old Foodie has an interesting series on the history and meaning of food coloring, both naturally-occurring and man-made. A few choice tidbits:- The crushed body of the cochineal insect, native to Mexico and South America, was the the original red food coloring. It's still possible to get cochineal dye, but it's expensive: It takes about 70,000 cochineal insects to make one pound of dye.
- Food coloring was sometimes used as paint for formal occasions. In 1846, renowned French chef Alexis Soyer painted a portrait of the Pasha of Egypt in pineapple cream for a state diner.
- Alfred Hitchcock once held a 'blue dinner party,' with blue-dyed soup, trout, chicken, venison, peaches, ice cream, bread and more. The guests were said to have been repelled.
