I was wondering if the 5 oz. sauce bottles with the plastic screw top lids work for hot water baths. I make hot sauce and would like an extra margin of safety in the preservation process. If these bottles/lids are not suitable, what would you suggest?
A: Hello Jack:
I’ve never done the water bath with jars with plastic rather than glass or metal lids, so I’m guessing a bit here. But physics tells us that the temperature of boiling water is 212 degrees F., which is far lower than the temperature required to melt plastic. The best thing would be to try a sample and see what happens before committing to a full batch.
