For Charred vegetables
- Grill the leeks until they get quite dark on the outside and vacuum pack them so that they continue to steam and cook through.
- Peel the outer layers until the centres are exposed and reserve the outer layers for the ash emulsion.
- Cut the leeks into 5cm rounds and season with salt and hazelnut oil.
- Peel the white asparagus and trim the tails, season with salt and rosemary and wrap them in aluminium foil.
- Roast them in a pan over a low to medium heat until the asparagus is cooked through and begins to char a little bit and also steam at the same time.
- Cut the asparagus into 7,5 cm pieces and reserve for plating.
