Once set, transfer some of the mixture to a piping bag and set aside in the freezer until needed.
• Take the Malt Meringues out of the oven. Being careful not to crack the meringue, use a fine microplane to gently file and flatten the underside of 8 meringue pillows to create a flat, smooth base. Using the microplane, gently file the curved top side of 4 of the meringue pillows to create a flat surface on both sides.
• Using a Parisian scoop, scoop out a portion along the underside of each of the meringue pillows to create a small crevice, being careful not to crack the meringue.
• Place the 4 meringues, which have been filed on both sides, onto a square white plate so that the scooped side is facing upwards. Pipe a little of the Milk Ice Cream into the crevice of the 4 meringues.
• Top each filled meringue base with a second, unfilled meringue, with the curved side facing upwards to create a closed pillow.

To serve:

• Very carefully place the 4 meringue pillows on to the floating pillow
• Use the rocher spoon to scoop out one rocher of Coconut Ice Cream place on to the Frozen Yoghurt Powder on each plate.
