We mix honey and sugar in a dipper and put on a small fire. Bring to a boil and cook to amber color, about 10 minutes. Add the oil at room temperature in parts. Pour in hot sour cream. Cook to the desired consistency. We check for readiness: drip a couple of drops of our mixture onto a cold surface, let it harden and try to find a consistency. Cover the baking sheet with parchment and grease it with butter. Pour the finished mixture and let cool, but not completely. Cut the soft iris with a knife into squares. Allow to cool completely.
