Mix dry ingredients together and evenly coat the racks of lamb.
Preheat the oven to 400 degrees F.
In a large, ovenproof saute pan, heat vegetable oil on high heat until lightly smoking. Carefully sear lamb on both sides quickly. Remove the pan from stove and place in the oven. Bake until lamb reaches an internal temperature of 120 degrees F. Cooking time will vary with individual's oven. Let chops rest for 5 minutes and then cut into portions.
To serve, place 1/2 of the truffle-taro mash in piping bag and pipe in round flower shapes on the plates. Serve 3 chops next to truffle taro mash. Drizzle some of the pineapple peach chutney on top of the lamb. Drizzle the berry jus sauce over and in front of the lamb.
Boil the potatoes until tender and drain. Steam the taro until tender. Pass both potatoes and taro separately through a ricer and into separate containers. Incorporate butter and cream into the Yukon mash and season with salt and pepper, to taste. Gently fold in the taro mash and truffle oil until just mixed. Adjust seasonings, to taste. Set aside.
Soak dried raisins and peaches in 1/2 cup of warm water to soften. Mix remaining ingredients in a bowl. Put all ingredients in a medium saute pan and cook on medium heat until the fruit is tender and the sugar begins to caramelize into a golden brown. Remove from heat. Remove cinnamon sticks, cloves and star anise. Set aside.
In a saucepan, add the lamb stock and bring to a boil. Cook until reduced to 1 1/2 cups.
In a separate, small, 2-quart saute pan, saute carrots, celery, and onions in vegetable oil until all vegetables are caramelized and golden brown in color. Pour in 3 cups of red wine and reduce until almost dry and no liquid remains. Add lamb stock, coffee, bay leaves, peppercorns, and thyme. Add fresh raspberries, (or substitute for any berry of your choice) and blackberry jam. Cook until reduced to 1 cup. Strain through fine mesh strainer and add salt and pepper, if desired.
