Canning Pressure

by Terrie

If canning at 15 lbs. pressure, could you reduce the time set for 10 lbs. pressure? What is the difference in the two pressures?

Most recipes call for 10 lbs pressure, but my weighted gauge is at 15 lbs.

Thanks
Terrie

Terrie, I would not change the time for your recipe. Even though the pressure you are using is higher, my recommendation is to keep the same processing time. It won't hurt to process higher but it could hurt to under process.
