I like to make Beef Stroganoff, but I’m never sure what cut of meat to use. Lately I’ve tried beef top round that the butcher cuts into cubes for me. My sauce is fine, but I think the meat should be more tender. I let it simmer for about 35 minutes. Is that the right amount of time? Any hints will be welcomed. —B.M., Pleasant Valley, New YorkBeef top round steak is generally a tougher cut and lacks in flavor. If you wish to use top round, I recommend cooking it for 1 to 1-1/2 hours over very low heat. Typically, Beef Stroganoff is made with more tender beef cuts, which decreases the cooking time to 30-40 minutes. You may want to try beef tenderloin or sirloin steak cut into narrow 2-inch strips. Leftover cooked beef can also be used. Add the cooked meat with the beef broth or other liquid and simmer for no more than 30 minutes.
