Wash the potatoes, cover and cook in plenty of water for about 20 minutes. Drain the potatoes, rinse with cold water and peel. Press potatoes while still hot through a potato ricer and let them cool down for 10-15 minutes. Sprinkle potato mass with about 1 tsp. salt and knead the flour with the dough hooks of the hand mixer bit by bit. Form the potato mixture into longish rolls (approx. 2 cm Ø) and cut into pieces of approx. 1 1/2 cm length.
Flatten with a fork. Boil up plenty of salted water in a large pot. Cook gnocchi in 2-3 portions in lightly boiling water for 3-5 minutes. When they are floating on top, remove them with a skimmer and let them drip off on a clean tea towel. Clean, wash and drain the rocket. Coarsely chop the walnut kernels. Heat butter in a pan, add walnut kernels, up to 1 tbsp. to sprinkle, fry lightly for about 1 minute. Add the gnocchi and toss in the nut butter for 1-2 minutes. Pour onto a preheated plate. Put truffle-tomato pesto and cream in the hot pan and heat while stirring.
