...and still have a rim that adds rigidity and accepts a tight lid. Right! Letís get down to work:
Get some Dinty Moore microwaveable stew. Iím partial to the chicken & dumplings.
Cut the aluminum rim off with a razor knife. Leave that bit of plastic inside the rim-youíll need it later.
Turn the rim upside-down, place it on your Heinie, and and chop the pot about an 1/8Ē above the new rim.
Make 16 evenly spaced cuts down to the new rim, bend the tabs parallel with the top of the pot, and round off the corners of the tabs with your scissors.
Finish bending all the tabs over the new rim with some needle-nose pliers.
Remember the plastic left in the rim? Heat the rim with a pencil torch(a lighter will work in a pinch). The plastic will expand and seal the tabs in place.
Seal up the lid from the Dinty Moore with some foil, Styrofoam, ccf, etc. Snap it on top your pot and youíre ready to cook*.
Disclaimer: Donít try to ďcookĒ with this lid. Itís suited for boil and dump, AKA freezer bag cooking. Boiling water longer than 3-5 minutes may result in small melted spots on the lid.
