Bring the pasta to the boil in 2 litres of water. Salt generously. Remember that the pasta must be over cooked.
Chop the celery stalk and cut the cold smoked salmon. Fry the celery in olive oil for a while in a pan. Squeeze in the lemon juice. Add the cream. Season with white pepper.
Add another 2 dl of pasta cooking water to the pan. Bring the sauce to the boil and leave to stand.
When the pasta is cooked, pour off the excess water and stir in the cream sauce and the chopped cold-smoked salmon. Chop the dill into the mixture.
Serve the Cold Smoked Salmon Pasta immediately garnished with dill sprigs.
