Sous vide tastes great but there WILL be plastics in your food. Both my parents have Alzheimer’s and I wouldn’t ever knowingly eat food boiled in plastic. I fear that too much plastic in us hurts us. I don’t know this for a fact but it can’t be good, sorry to be a total Debbie Downer. I’ve heard how perfectly sous vide cooks steaks. There are some silicone bags but they don’t have a perfect seal yet.
