>> washing-up: the large skillet, a plate for the seared beef
>> keeps: 2 days — the noodles swell whatever you do, so boil them fresh if you know you are making it ahead

Sour cream splits if it boils, so the pan comes off the heat before it goes in. If the sauce looks tight, loosen it with a spoonful of hot water.
