Is it safe to cook in a clean Teflon pot if the inside bottom has blistered and peeled from exposure to high heat?
You can just treat it as a regular metal pan now, and season it with oil and high heat

Though, first you have to remove all the flaked coating with a hard metal scourer. This may prove difficult!

Have done this to a few pans, and they work well as plain metal pans. Somewhat easier to use that plain steel, as they are aluminium and therefore lighter on the hand
