Gently Cooked Sous-Vide. Sous vide is a low-heat cooking process that lets the whole food ingredients retain all of the important nutrients. Foods are in vacuum-packed bags and cooked in water at a specific temperature (A Pup Above uses 180 degrees to ensure there are no issues with Salmonella or Listeria contamination) for perfection every time. Additionally, all the nutrients of whole-food cooking remain.
