Coffee porter, malt and pecan

Begin by preparing the ice cream. Add the reduced Porter, espresso, milk, vanilla pods and instant coffee to a pan and bring to just below boiling point. Meanwhile, add the sugar and egg yolks to a heatproof bowl and whisk together until pale

Slowly pour the contents of the pan into the egg and sugar mixture, whisking to combine, then transfer back to the pan and cook until the mix reaches 82°C. Stir in the whipping cream, then freeze the mixture in Pacojet containers and blitz for 1 hour before using. Alternatively, churn in an ice cream maker according to manufacturers instructions

Preheat the oven to 180°C/gas mark 4

For the tart, melt the butter in a pan over a medium heat and, once melted, add the golden syrup, malt, beer and double cream. Whisk together until combined, then add the egg and egg yolks to the mix, whisking in quickly. Add the lemon juice and whisk again to combine

Pour the mix onto the oats and mix to combine. Spread the mixture out in a 10 x 10cm shallow, lined baking tray and bake in the oven for 30 minutes. Once baked, allow to cool to room temperature

To prepare the candied pecans, which will be used in the parfait and as a garnish, add the sugar to a pan and heat until a light caramel forms. As soon as it reaches this stage, remove from the heat, add the toasted pecans, then transfer to a tray and allow the candied pecans to cool

Once cool, break into a coarse crumb, keeping half for the parfait and the other half for garnish

For the parfait, add the milk, vanilla pods and extract to a pan and bring to the boil. Meanwhile, whisk together the egg yolks and sugar in a heatproof bowl, then whisk half of the boiling milk into the egg mix until combined

Pour this back into the pan with the milk and cook to 85°C. Add the gelatine, stir to dissolve and pass through a sieve into a bowl. Allow the mixture to cool completely, then fold in the semi-whipped cream

Fold in half of the reserved crushed pecans, then transfer to a piping bag. Pipe into silicon circular moulds and place in the freezer until completely set

To serve, slice the tart into thin slices and divide onto plates. Warm the outsides of the parfait moulds, then turn out onto a surface, cut in half and place a half onto each plate. Sprinkle the pecan crumb on top, followed by some whole and roughly chopped pecan halves and a quenelle of the ice cream. Serve immediately
