Foodsavers work! With risotto, leave it in the freezer vacuum bag and boil or slow heat the pouch. Serves it almost fresh tasting!
do I completely cook the risotto before putting it in the bag?
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.
