Blob, are you talking about something like this ?FoodSaver® Wide Mouth Jar Sealer
Can I use this to seal the lid on a jar and than remove the adapter or does it become the lid and stay on the jar? The web page doesn't say. Thanks
Blob, are you talking about something like this ?FoodSaver® Wide Mouth Jar SealerYou can buy the mason jar attachment for about $10 & then attach an automotive brake 'bleeder' hand pump (for $20) to vacuum out the air @ 25-30 psi (it has a gauge), if you don't feel like shelling out $100+ for a food vac.
