Just for fun:
Beef Stroganoff or beef Stroganov (Russian: бефстроганов befstróganov) is a Russian dish of sautéed pieces of beef served in a sauce with smetana (sour cream). From its origins in mid-19th-century Russia, it has become popular around the world, with considerable variation from the original recipe. (Wikipedia)
Our neighbors, Boris and Natasha would love Mom's recipe! I'll have to send it over and see how our comrades' recipe compares to my own. XO
"You might be surprised but potatoes is the most traditional pairing for Beef Stroganoff in Russia. Mashed potatoes at home and often fried shoestring potatoes in restaurants. Try them, you won’t be able to go back to egg noodles." (https://vikalinka.com/best-beef-stroganoff/)
I was surprised to see the variations out there - some with wine, some with tomato sauce, some with onions... Have fun!
