Broken down, your basket of "sweets" includes: a shape-holding protein derived from animal skin, a sidewalk de-icer, and the pulverized center of the cacao bean.
...and insect fragments, post harvest and/or processing insect infestation, rodent hair, post harvest and/or processing contamination with animal hair or excreta, cigarette butts, burlap, stone fragments... lots of yummy stuff.
