Steps

  • Turn the ice cream machine and blast chiller on to pre-chill. Warm the sous vide machine to 85°C.
  • Meanwhile, preheat the oven to 75°C.
  • For the Lemon Verbena Meringue, half fill a medium saucepan with water and place over high heat.
  • Combine the caster sugar and egg white powder in a medium bowl and whisk. Add the egg whites and whisk to combine. Reduce the saucepan to low heat for a gentle simmer. Place the bowl over the saucepan of simmering water. The bowl should not touch the water.
  • Whisk the meringue mixture constantly until the sugar has dissolved totally and the mixture has reached 73°C.
  • Transfer the meringue mixture to the bowl of an electric mixer, fitted with a whisk attachment. Beat on high speed for 3 minutes.
  • Add the citric acid, lemon verbena flavour drops and lemon verbena powder to the meringue and whisk until stiff peaks form.
  • Scoop three quarters of the Swiss Meringue into a piping bag, reserving one quarter to make the discs.
  • Place the dome moulds on the scales. Cut the tip off the piping bag and pipe 15g of meringue into each semi-sphere mould, over the inside walls in a spiral. Place the moulds on a flat oven tray.
  • Using the back of a dessertspoon spread the meringue against the inside sides and base of the moulds to make a thin, smooth and even shell.
  • To make the meringue discs, place a silpat mat on a flat oven tray. Place the plastic 2cm disk stencil on top and use a medium offset palette knife to spread the reserved meringue into the holes.
  • Using a small sieve, dust the extra lemon verbena powder over the meringue discs. Remove the stencil.
  • Bake the meringues on the middle shelf, with meringue disks underneath for 3 hours or until completely dried out. Allow the meringue to cool.
  • For the Lemon Verbena Milk Infusion, place the milk in a medium saucepan and bring to the boil over high heat. Remove the saucepan from the heat. Add the fresh lemon verbena leaves. Transfer the milk and leaves to a ½ size deep gastronorm and chill in the fridge for 1.5 - 2 hours to infuse.

  • Add both the purees and the liqueur. Process once more with the hand blender to emulsify.
  • Transfer the sorbet mixture to the ice cream machine and churn until softly frozen. When softly frozen, transfer the ice cream bowl to the freezer and freeze until required.
  • Meanwhile, for the Lemon Verbena Jelly, make sure that the mix is cool. Add the lemon verbena powder and stir through.
  • Spray a 16x26cm, 3cm deep oven tray with canola spray and pour the jelly into it. Chill the jelly in the fridge for 30 minutes or until set.
  • Meanwhile, for the Pear Puree, peel the pears, remove the core and thinly slice.
  • Place the pear, ascorbic acid and stock syrup into a sous vide bag and vacuum seal to 30cm length, ensuring the liquid isn’t sucked into the machine.
  • Flatten contents of the bag on the bench to an even layer. Place the bag in the sous vide machine and cook at 85°C for 25 minutes or until the pears are tender.
  • Meanwhile, for the Compressed Pear Pearls, combine the stock syrup, liqueur, lemon puree, chardonnay vinegar and lemon verbena leaves in a food saver vacuum pac container.
  • Peel the skin from the pears and using a 12mm Parisian scooper, scoop the flesh to make 16 small pearls.
  • Place the pear pearls into the verbena syrup, place the lid on top and compress using the vacuum pac machine until the green indicator on the container indents.
  • Chill the compressed pear pearls in the syrup in the fridge until required.
  • For the Pear Puree, process the pears and the cooking liquid in the Thermomix, until smooth, scraping down the sides. Place a clean Thermomix jug onto scales and pass the puree through a fine sieve into the jug. Record the weight of the puree.
  • Place the jug back into the Thermomix machine and warm to 100°C on speed 2.
  • Calculate 1.5% of the total puree weight. Add that quantity of Gellan F to the puree mixture.
  • Process at speed 4, 100°C for 10 seconds. Stop and scrape the lid and walls of the Thermomix with a spatula to make sure that the Gellan F is incorporated into the puree. Continue to process the puree on speed 4, 100°C for 2 minutes or until smooth.
  • Add the puree to a ½ size shallow gastronorm and spread into a thin layer. Transfer the tray to the blast chiller and leave for 5 minutes or until set to a firm gel.
  • Break up the gel, return to the Thermomix and process until smooth. Add the water and process to combine. Place the puree into a vacuum machine bag and seal, removing excess air.
  • Transfer the puree to a squeeze bottle and chill in the fridge until required.
  • For the Lemon Verbena Jelly, once set, cut into 5mm cubes. Reserve in the fridge until needed.

  • For the Pear Disc and Soaking Syrup, combine the water, syrup and ascorbic acid in a small bowl and whisk until the ascorbic acid dissolves.
  • Using a mandolin, slice the pear into 5mm thick slices. Use a 2.5cm round cutter to cut 20 small discs. Transfer them to the syrup and chill in the fridge until required.
  • When the Meringue Domes are cool, use a microplane to lightly grate the rounded base of the meringue dome to create a flat and stable base. Lightly grate the top edge of the dome to create a flat edge. Place Meringue Domes in an airtight container with silica beads.
  • Transfer Apricot Nappage to a small glass bowl, cover with plastic wrap and set aside.

To assemble the dessert:

  • Place a 10cm round cutter in the centre of the plate. Place a 5cm ring covered with cling film in the centre of the 10.5cm cutter. Brush the space on the plate between the two round cutters with the Apricot Nappage.
  • Dust the Nappage with Lemon Verbena Sugar through a small fine sieve. Use a clean dry pastry brush to clean the plate outside the 10.5cm cutter. Carefully remove the cutters. The final product should resemble a ring.
  • Place the Meringue Dome on a clean set of scales. Inside the walls of the Meringue Dome, pipe 25g of the Lemon Verbena Cream, leaving a centre cavity. In the middle, add 15g of diced Lemon Verbena Jelly, 5g of Pear Puree, 8 Pear Pearls and 1 scoop of Pear Sorbet. Pipe 25g of Lemon Verbena Cream around and over the Sorbet and other fillings to cover.
