Question for the Sous Vide masters. Can I re-use the lids for my cheesecake jars? Just curious if they reach a high enough temp to ruin the seal. I've been making a ton of mini cheese cakes lately,( lemon curd are my favorite) and have ended up with a ton of used lids. I know I can keep buying them, but seems like a waste if I can re-use them. Please advise.
