Food Science?: Chocolate Agar Plate
What is an agar plate? Agar plates are commonly used in biology labs. An agar plate is a Petri dish containing a growth medium used to culture certain microorganisms.
There is a type of agar called chocolate agar (see photo above). Unfortunately there is no actual chocolate in the agar; it's name is chocolate because of the color of the agar. Chocolate agar comes from cooked blood (yummy!) and is used to culture fastidious (fussy) organisms.
So a note to all of you bio students/researchers/dabblers: DO NOT EAT YOUR CHOCOLATE AGAR...it is not made of chocolate. Go buy a bar of the goodstuff to satisfy your cravings.
