Finely chop the chives. Cut the smoked tofu into strips about the length of the pasta.
Clean the spring onions and cut into fine slices. Mix the egg yolks with the cream, the parmesan and the sliced spring onions, season well with salt and pepper.
Now put the pasta in boiling salted water and cook until al dente.
Meanwhile, heat peanut oil in a non-stick pan and fry the smoked tofu until golden, then add to the egg-cream mixture.
Drain the pasta, collecting some of the cooking water. Put the pasta back into the hot saucepan, pour the cream, egg and tofu mixture over it and stir, adding more cooking water if necessary.
Arrange on plates and sprinkle generously with the chives and, if you like, with additional parmesan.
