Nightmares of blueberry cobbler

I wonder how cobbler came to mean a sort of pastry filled with cooked berries or other fruits? A cobbler is someone who fixes footwear. The idea of the semantic drift is truly staggering.

• Repairing a shoe * Filling the shoe with a foot after reparation * Allowing the shoe to become a crumbly pastry * Detaching the foot from the remainder of the body * Allowing the meat of the foot to become vegetarian * Making sure the vegetarian items within the ex-shoe is now a fruit * Popping the whole thing into the oven * Feeding the result to southern geezers in casinos or upscale hotel buffets

Yeah.
