Finely chop and saute the
onion. Add the finely chopped tarragon keeping a little back for garnish. Add the creme fraiche and Marsala and reduce.
Season to taste. Meanwhile add the fresh pasta to boiling water and cook for
2-3 mins until al dente. Just before serving add the smoked salmon to the sauce
and serve on the pasta. Garnish with remaining tarragon. Delicious with a crisp
salad and a glass of prosecco.
