Make the gnocchi:
Cook the potatoes in their skins in salted water until done.
Peel them while they are still warm and mash them finely.
Mix with the egg, a pinch of salt, and enough flour to make a soft, non-
sticky dough.
Roll the dough into long sausages and cut into small pieces.
If desired, press ridges into the gnocchi with a fork.
Bring a large pot of salted water to a boil.
Cook the gnocchi until they float to the surface, then they are ready. Scoop them out with
a slotted spoon and reserve some cooking water for the sauce.
Make the Spinach sauce:
Bring water to a boil and poach the spinach briefly until it wilts.
Drain, rinse with cold water if desired, and squeeze out very well.
Chop the spinach coarsely.
Combine the spinach with: the Parmesan cheese, the anchovies, the olive oil, pepper and salt, and a splash of cooking water.
Blend (or 'cut') everything into a smooth, creamy sauce. Add extra
cooking water if needed for the right consistency.
Caramelize the kohlrabi:
Cut off the bottom fibrous piece of the kohlrabi.
The skin can remain on.
Cut into thin slices, then into strips, and finally into small cubes (brunoise).
Heat 2 tablespoons of olive oil in a large pan.
Sauté the finely chopped garlic gently until it starts to smell and turns light brown.
Add the kohlrabi, season with pepper and salt, and let it caramelize slowly over medium-low heat. This takes about 15–20 minutes. Stir regularly to ensure it turns a nice golden brown without burning.
Finishing touches:
Add the cooked gnocchi to the pan with kohlrabi.
Spoon the spinach sauce over it.
Gently but thoroughly mix everything.
Finish with extra Parmesan cheese and a drizzle of olive oil.
Serve immediately.
