I’d say that your stressing the word зеленый was approapriate, but not necessary at all. If you hadn’t stressed it I would never have started thinking about the “репчатый” onion that you have already fried, even without watching your video and only listening.
Then, it should have been поставить в духовку instead of посадить в печку. We extremely rarely call the kitchen stove печка. We call it плита. When I hear someone saying Я купил новую печку I’m always like, “What? Oh, I see." But the place you put the caviar at the end of your cooking is духовка. Поставить в плиту would be impossible, too.
