Stroganoff was named after a Russian diplomat Count Paul Stroganov. Traditionally it is made with tender cuts of beef, such as filet, but in this recipe let’s try to be a little more realistic. Not all of us are Counts.
To prevent curdling, have sour cream at room temperature. “Temper” the sour cream (mix a little of the hot broth into the sour cream, then incorporate “tempered” mixture into pan). Reheat gently, but do not bring to boiling point or the sauce will curdle or “break”.
If you decide to use a better cut of meat (bourgeois! fru, fru!), the simmering time will be significantly reduced.
