Begin by melting the milk and white chocolate. Cut 4 sterilized, food-safe flexible plastic strips 1 1/2 inches wide and 5 inches long. Spread a thin layer of milk chocolate on the plastic strips. Using the tine of a fork, scrape the length of the strip through the chocolate to create lines. Spread a layer of white chocolate immediately, directly over and then fold to form a ring. Seal edge with a plastic strip. Set aside to harden.
Preheat the oven to 360 degrees F.
Mix the sponge by whisking the eggs and sugar on high speed for 15 minutes, until pale yellow and thick. Take out of the mixer and fold in by hand the sifted flour, chopped macadamia nuts, and melted butter. Spread thinly on a buttered, floured and parchment lined baking tray and bake for 15 minutes.
Lower the oven to 340 degrees F.
To roast pineapple, begin by cutting the pineapple into grape size pieces and then toss in sugar and spices. Bake for 2 hours. Let cool.
To caramelize the macadamia nuts, first warm the nuts in the oven for 5 minutes. While nuts are warming, place the sugar in a small saucepan and cook over medium heat until the sugar melts and turns an amber color, about 10 minutes. Carefully add the nuts to the sugar mixture and stir to coat the nuts. Carefully remove from the pan and cool on a marble table or baking tray.
To make mousse, boil the milk, remove from the heat and add the gelatin while mixing in the white chocolate. Cool down slightly before folding in the whipped cream.
To make the jelly, melt the gelatin with the mango puree and strain into a container for future use.
To plate, place a circle of sponge in the base of the chocolate ring, sprinkle with chopped caramelized macadamias. Pipe 1/3 of the cup with mousse; place a spoonful of pineapple mix, top with mousse and a layer of mango jelly. Place in the refrigerator for 1 to 2 hours. Once chilled, remove the plastic strip, top with caramelized macadamia nuts and macadamia sponge.
