Briefly toast the kernels in a coated pan. Add the olive oil and then add the garlic, chilli peppers and the crayfish meat and sauté. Mix with the crème fraîche, season with oregano and basil. Season to taste with salt, pepper, pesto and, if desired, white wine. Mix the rocket into the sauce just before serving.
Meanwhile, cook the noodles in salted water until they are al dente and serve with the sauce.
A dry white wine goes well with it, e.g., Pinot Grigiot.
