Anova precision vacuum sealer

What it is good at

• Preventing freezer burn over months rather than weeks
• Marinating quickly under vacuum
• Compressing portions so a small freezer holds more

Check before you buy

• Whether it handles both channel bags and rolls
• Whether a moist-food or pulse mode is included for wet marinades
• Bag cost per use, which is the real running cost

Who it is not for

Anyone who freezes rarely and has a small freezer; zip bags and a straw of air are enough.

Vacuum sealing is about the freezer, not the pantry. The saving is in the food you do not throw away because it turned grey in three weeks.

The machine is cheap compared to the bags. Check the price of bags in the size you will use before choosing a brand.
