--------  ------------  --------------------------------
     1/2  cup           fresh lime juice
   3      tablespoons   peanut oil or vegetable oil
  24                    green peppercorns -- crushed
                        salt
                        freshly ground black pepper
     3/4  pound         sea or bay scallops -- finely chopped
   1      large         ripe avocado -- peeled
   2      tablespoons   fresh chives -- chopped
                        scallions -- chopped
  40      small         white mushrooms
     1/4  cup           vegetable oil
   2      tablespoons   fresh lemon juice
   1      medium        garlic clove -- peeled and crushed
                        salt and pepper to taste
                        additional chives -- optional
                        (or scallions) -- for garnish

Preparation:

COMBINE THE LIME JUICE, oil, peppercorns, salt and pepper together in a glass or ceramic bowl. Stir in the scallops, cover and refrigerate for at least 4 hours while they marinate. They should become opaque in this time. Mash the avocado until almost smooth, then add it along with the chives or scallions to the marinating scallops (do not drain them) and mix well. Set aside for at least 1/2 hour, refrigerated. About half an hour before serving the scallops, remove the stems from the mushrooms and wipe them to remove any dirt. Combine the vegetable oil, lemon juice, garlic, salt and pepper in a small bowl, and brush the insides of the mushrooms liberally with the mixture. Just before serving, drain the caps and fill with the scallop mixture. Garnish with additional chives, if desired.
