Joseph,
This is one of my favorites.
As explained earlier, make a boat out of aluminium foil. Put your tea, rice, brown sugar mixture in it and place in the smoke house. I prefer to use oolong tea, one-half wild rice/one-half basmati rice, and deep brown sugar. This produces a deep coating on the duck. The duck carcass is rubbed with Black Salt (if available otherwise regular sea salt) and Black Pepper (I also use Szechuan Pepper in the rub). I stuff the cavity with chopped green onions (scallions) orange or tangerine slices, and chopped shallots. Also, it is wise to prick the duck with a fork all over to let the grease out. For a more crispy skin you will want to finish in an oven at at least 400 deg. Fahrenheit.
Good luck and Bon Apetit!
Gilly
