This is a very simple (and truly non gourmet-but addictive) side dish that for some reason I associate with salmon. Of course it could accompany any number of main courses but I think it would pair best with chicken, pork or veal rather than beef or lamb. In order to make the dinner process easier, I often prepare this ahead and reheat it in the microwave just before serving (perhaps with a bit more sour cream if it seems dry). There are no precise amounts given. Here your taste buds are your friend.
The dish is as follows:
Boil elbow (small) macaroni in salted water until done. Drain and toss with butter. Salt and pepper to taste and add sour cream to give it an almost creamy consistency. Check seasonings and serve at once, or cover and put aside and reheat in the microwave adding more sour cream if it seems too dry.
