Barbecued Oysters with Shiitakes

      1 tb Chinese oyster sauce               12 md To large fresh shiitake caps
      1 tb Hoisin sauce                             Olive oil
      2 ts Ketchup                            12 ea Fairly large oysters,
    1/2 ea Serrano chili, seeded and                -shucked
           -finely chopped

  Pre-heat oven to 325. Combine the oyster sauce, hoisin sauce, ketchup and
  serrano chili.  Let the mixture sit for several minutes to let the serano
  flavor the sauce.  This step may be done well ahead. Make sure the stems
  are completely cut off the mushroom caps. Paint the caps with a little oil
  and a little of the sauce. Place them on a baking sheet and bake in the
  preheated oven for 2 minutes. While the caps are baking, roll the oysters
  in the rest of the sauce so that they are evenly coated. Remove the caps
  from the oven and place an oyster on each cap. Return them to the oven for
  about 6 minutes. Remove and place on serving dishes and serve immediately.

Note: Yeah, I know, it's NOT BBQ, but it's too damned good to pass up.  Besides,
I wanted to see if you were paying attention.
