For the Duck:
The day before, trim and pat dry the duck legs. Season with five spice. Mix thyme, rosemary, garlic, peppercorns, lemongrass, lemon, orange, cloves, salt, and sugar in a food processor and blend to a powder. In a pan, lay 1-inch of the powder and arrange duck legs on top, skin-side up. Place the remainder of the powder over the legs, thoroughly covering them. Let cure for 18 hours. The next day, remove the legs, rinse, and pat dry. In a pan, bring the duck fat to 100˚F. Add the duck legs and transfer to a CVap set at 140˚F with zero browning for 24 hours. Remove from CVap and let cool in the fat. Reserve.
For the Cashew Butter:
Place the nuts and butter in a pan over low heat. Toss until butter starts to brown and transfer to a food processor and pulse into mixture turns into a paste. Add the honey and continue blending until thick. Season with lemon juice and salt. Reserve.
For the Candied Lime:
Peel off the rind of the limes and julienne. In a blender, juice the limes, strain, and reserve liquid. In a pot, add julienned rinds and water. Bring to a boil and strain. Add orange juice, sugar and cinnamon and reduce to syrup over low heat. Add lime juice, reduce again to syrup and reserve in a cool place.
For the Tamarind Emulsion:
Reduce orange juice to syrup consistency. Add to blender with soy, tamarind and peanut butter. Set blender to slow speed and incorporate oil. Season with lime juice and salt. Reserve.
For the Banana Brulee:
In a bowl, work the butter with the ginger snaps until pliable. In a pan, add butter and plantains. Cook until caramelized and season. Crush with a fork. In six small 8-ounce cast iron pots, line the bottoms with the butter and ginger snap mixture and press until crust is set. Fill pots with crushed plantains and smooth the top. Shingle the top with banana slices and sprinkle with sugar. Caramelize tops with a blow torch.

Lay the Duck over the butter and place a few strands of Candied Lime on top. Arrange Tamarind Emulsion in stripes on the plate. Serve Banana Brulee on the side. Garnish with micro-benitade sprouts.
