For the pear parfait sponge base, preheat the oven to 180°C. Whisk the eggs and sugar until they reach the thick ribbon stage, then fold in the sifted flour.
Using a pallet knife, spread the sponge about 2mm thick onto a Silpat and bake for 5-6 minutes in the preheated oven. Leave to cool.
Place a metal rectangle 28cm x 18cm x 4cm on top, cut the sponge to size and set aside.
For the pear parfait, in a bain marie whisk the egg yolk, sugar and water until it reaches 78°C then transfer to a mixer with a balloon whisk and whisk the sabayon until aerated, cold and doubled in volume.
In a separate bowl whip the cream, pear purée and liqueur until ribbon stage.
Fold the cream into the sabayon, and immediately transfer the parfait mixture to a lined metal pastry mould and freeze for a minimum of 6 hours.
For the liquorice and pear sorbet, make the stock syrup by bringing the water, sugar, glucose and lemon juice to a boil and then simmer for 5 minutes.
Mix the pear purée with the stock syrup and liquorice concentrate, leave to cool, churn the sorbet and then freeze.
For the liquorice jelly, in a small saucepan bring the water, sugar, liquorice concentrate and agar to the boil and simmer for one minute. Remove from the heat, drain the gelatine and stir it into the hot liquid. Pour the jelly into a small container, leave to cool and set.
For the poached pears, peel the pears, cut them in half, and remove the core.
In a large saucepan dissolve the sugar in the water; add the liquorice root, cinnamon stick, star anise and the juice and zest of the lemons.
Bring the stock syrup to the boil, simmer for 5 minutes, add the pears, cover with a cartouche, reduce the heat and poach the pears until tender to the knife point. Leave to cool in the syrup. Cut the pears to size before serving.
To serve, with a hot knife slice a piece of the parfait, place it on a cold plate, decorate with small squares of the jelly, poached pears and a small scoop of the sorbet, dust with liquorice powder and serve.
