The world is linked in fascinating ways. In Peru, workers roam the hillsides collecting millions of female cochineal bugs from their cactus pad nests. After dunking in hot water, drying and grinding, the bugs make an excellent red dye. The dye is used to color many products including yogurt (look for carmine in the ingredients), red Smarties, and even lipstick!
