The canner began coming to pressure, steam started shooting under the pressure gauge.
The jars began to seal when I opened the canner to fix the gasket. I reprocessed them all without putting new lids on (some were sealed), will the food still be good in those sealed jars?
If the canner pressure dropped suddenly from high pressure (either because a valve or gasket failed catastrophically, or because you quick-released the pressure), I might worry about the contents having boiled up, compromising the seals. But if the canner just failed to pressurize on the first try because of a leaking gasket, I don't see any reason for concern.
