There’s also room for maneuvering; add more or less wine or cream to taste; leave out the pine nuts if you can’t be bothered; add some asparagus or cream cheese if you want; use smoked trout or sturgeon instead of the salmon. The essentials are smoked fish, lemon, garlic, and pasta with some olive oil, wine, and or cream binding them together. Once the pasta is done, and before draining the pasta, scoop out one cup of the pasta cooking liquid and reserve. If you want a slightly creamy sauce, add the cream and let boil a minute more. The sauce should be done about the same time the pasta is done. If you get done earlier with it than the pasta, take it off the heat.
