Instructions: *Preheat oven to 350F. Thinly slice the scrubbed potatoes. Brush a bakers sheet (large, heavy) with clarified butter; arrange the potatoes in a single layer on the sheet. Brush tops of potatoes lightly with clarified butter. Salt and pepper, if using. Bake 15 to 18 minutes or until done, not browned. Remove.

From oven

*Meanwhile, heat unsalted butter in a large saute pan over medium. Add the leek, mushrooms, zest and ground coriander seed; heat then add the mirin, salt and pepper (if using). Soften for 10-15 minutes.

*Preheat oven to 475F. Make Parchment-paper envelopes: Fold single sheet of parchment paper in half (to form squate) then cut large heart-shaped piece, like a Valentine. Open and assemble potatoes, leeks, chanterelle, mushrooms, bay scallops and a dollop (2 tablespoons) of truffle butter.

Fold and turn the cut edges into a hem that seals the envelope.

Makes 10 to
15 minutes; serve in the paper; cutting an opening or lid in the top. Serve with the mango sauce, garnished with tarragon just before serving.

METHOD: Food that cooks quickly, like chicken and seafood, lends itself to the "en papillote" steaming technique (French for "in paper"). Choose a couple of flavorful ingredients, like shallots and truffles or parsley and lemon, and let them infuse a dish. The heart swells, and in a brief time creates a dish that is moist, with flavorful broth.
