Thaw the shrimps, wash them, pat dry, if necessary cut in half or quarters and fry in a little oil until they are nice and pink.
Wash the rocket and cut into small pieces. Coarsely grate the cheese. Finely chop the chilli pepper (if you don`t like it so spicy, only use half a pod!).
Heat the crème fraîche and add the rocket, mix in the shrimp, chilli and cheese and stir until the cheese has melted. Season to taste with salt and pepper.
Drain the pasta, mix with the sauce and sprinkle with fresh basil and serve immediately.
