Line the loaf mould with parchment paper on all sides.
In a pot, combine brown butter, smoked garlic, thyme, rosemary, sage, bay leaf, and Debic Cooking Cream.
Cook over the lowest heat for 30 minutes, stirring occasionally.
Strain the cream, pressing the aromatics until almost dry to extract maximum flavour.
Whisk the egg yolks into the infused cream to create the crème royale.
Using a mandolin, slice the potato into thin, even slices.
Layer the potato slices in the mould, brushing each layer with crème royale.
Cover the mould with aluminium foil and bake at 160°C (fan ventilated) for 1 hour.
Cool and refrigerate overnight.
Cut the chilled pavé into 3 x 3 cm cubes.
Roast in the oven at 220°C for about 10 minutes, or until golden brown.
