How are M&M's made?
Sigiloso
When a Mommy M and a Daddy M love each other very, very much.... Seriously, they make the chocolate first, cool it, separate them into their smaller spheres, then put into Panners where the sugar layers are added, dyed the different colors, then waxed (no kidding, very thin layer though). Then they go down a conveyor belt to get the M stamped on them.
