For the asparagus:
Cut asparagus into halves, lengthwise. Slice halves in thirds and then cut in pieces, each 4 cm long. Sauté asparagus in butter, season them, add poultry broth and cook. Keep asparagus broth for further processing. Mix leek with asparagus and season it.

For the sweet potatoes:
Season sweet potatoes with sea salt and drizzle with olive oil. Wrap in aluminum foil and cook in the oven at 160 °C for ca. 40 minutes. Peel and slice in evenly pieces and sauté in butter with lime peel and Piment d’Espelette.

Our Tip:
Dry cooked sweet potato peel in the oven at 80 °C overnight and roast it in a pan until it is crunchy. Afterwards season the chips with salt.

For the lemon foam:
Put all ingredients in a jar and froth it with a mixer until you have an emulsion that can be put in the siphon. Close siphon and put in 70 °C warm bath. Shake from time to time so that the egg does not clot.

Serving:
Spread asparagus, leek and sweet potato on the plate, drizzle with lime foam and scatter leek slices on top to finish the dish. Garnish plate with your sweet potato chips.
