Thanks to one of my observant readers, I have discovered a new gadget for vacuum-sealing Mason jars full of lettuce, fresh fruit, seeds, flour, nuts, etc. I have included a how-to video because I want all of my readers who use Mason jars for storing food to know about it.
Why I Love This Mason Jar Sealer
- Powerful Seal: Tighter and longer-lasting seals than countertop models.
- Keeps Food Fresh: Perfect for lettuce, nuts, seeds, flour, and more.
- Compact Design: Small enough to fit in a drawer, rechargeable, and easy to store.
Important: Vacuum-sealing is not a substitute for heat or pressure canning. Perishable items (e.g., lettuce, dressing, mayonnaise) must be refrigerated. Do not use for canning meat or cooked vegetables like tomatoes or green beans.
