Jamie at SV Homewares sent us a box of Jumbo Sous Vide Magnets to try. Jamie is a sous vide cooking enthusiast and entrepreneur who created SV Homewares to develop products for the sous vide space. He was also kind enough to provide me with some additional details and some of the justification for his design decisions in creating these sous vide magnets. I hope you find these interesting and beneficial as well.
Jason and I have been using these "red" magnets for a while now and they have turned into our "go to" solution to the how to prevent sous vide bags from floating.
