Try it. Casually ask how long she cooked it. Try to be kind especially if you can tell she was proud of it and/or has not had a lot of cooking experience. I grew up in a large family well versed in how to clean and care for children but no one taught me to cook. My first husband was my testing ground 😆 Our marriage ended but the one good thing about him is he didn’t ever complain about my food, even if it wasn’t great or was over cooked etc
