Cooking time without cooking mashed potatoes. Puree can be cooked in advance, take yesterday’s or prepare right before cooking cutlets. I had yesterday’s mashed potatoes from the fridge, made with milk, with a generous slice of butter added. She took the cold puree, broke an egg into it, and added cornmeal. Carefully vymenila, tried the salt and a little doolie. Finely chopped fresh herbs :green onion and dill. Added and evenly mixed in the mass.
