Chicken cutlets tender

I've been cooking this recipe for exactly ten years. He always helps out when you need to quickly and deliciously cook something from chicken fillet. Although you can use any other chicken meat, at least from the thighs. I insist on cutting meat, after a meat grinder or blender, a slightly different consistency of minced meat will turn out, and there is more fuss. Instead of sour cream, you can put mayonnaise, then the amount of salt should be adjusted. I have met recipes where cream cheese was added to such cutlets, but this is if you lose it) And even avocados! But simple sour cream is no worse, believe me! Take any flour you have. You can take starch, also any. You can marinate meat as much as you like, from half an hour to two days, but I often start frying after ten minutes. Although, if you wait, it will certainly taste better. I make cutlets flat, like pancakes, and they cook faster. But then I still bring it to readiness under the lid. I feel safer this way. There is another option after roasting to put the cutlets in the oven for about five minutes. And according to this recipe, wonderful fish cutlets are obtained, even children eat them! With meat, I think it will also work, it will only be necessary to cut smaller, marinate longer and fry under the lid.
