Vacuum bags usually mean a clunky machine and plastic that gets thrown away after one use. These bags from Zwilling's Fresh & Save range work differently. They close with a zip, are emptied of air through a valve using a small Fresh & Save pump, and can be used again and again.
Use them to freeze meat and fish, store cheese and cold cuts in the fridge or marinate under vacuum. The bags withstand up to 92 °C, so they also work for sous vide, and they can be frozen down to minus 18 °C. Every bag has a field where you can write what's inside.
Available in three sizes. S measures 23 x 20 cm and comes ten to a pack. M measures 35 x 26 cm, holds 4 litres and also comes ten to a pack. L measures 49 x 30 cm and comes three to a pack. Pump sold separately.
