This idea that it's not a good idea to cook over high heat with olive oil is fairly common. For a lot of people, the concern is one of health, specifically that olive oil, with its relatively low smoke point of 325 to 375Â°F (165 to 190Â°C), degrades more than other oils when exposed to high heat.
Pressure canning is the only way to fresh preserve at 240Â°F. (Boiling water canners heat to only 212Â°F which is the temperature of boiling water.) Because Clostridium botulinum spores do not grow in the presence of acid, high-acid foods can be safely processed in a boiling-water canner.
