Buying advice
Four options: 1) Binder clips on the tub edge, 2) magnetic weights on steel pots, 3) a rack that pins bags down, 4) a heavier bag setup (double-bag or a spoon inside the bag). For fattier foods, combine a weight with a clip — they float hardest.
FAQ
Why does my bag float?
Trapped air plus the buoyancy of fat — the more air, the more it floats. Squeeze the air out before sealing.
Is floating really a problem?
Yes — exposed parts cook slower and unevenly. It's worth a 30-second fix.
What's the easiest fix?
A binder clip on the tub rim — it works with any container and costs nothing.
