You would eat Ner Mitzvah EVOO?
Sorry yfr bachur, I have to agree with Shmuel K (and ushdadude) on this one.
Ner Mitzva sells Extra Virgin Olive Oil? Pics plz.
His point is that extra virgin olive oil is by definition edible. It's oil extracted using mechanical means, not chemicals (or heat), and has a low enough acidity take it edible.
Pressed oil with too high acidity is not called Extra Virgin, it's lampante. The lighting oils are usually not even that (according to what small research I did,
@moko probably knows more) and are instead refined or pomace oil, meaning oils extracted from the pulp and seeds, using heat and chemicals, and/or refined to make them more stable, remove and bad taste, and raise their smoke point.
That stuff lichora A) is not the shemen zayis of the gemara, even if it came from an olive B) I'd assume a higher smoke point oil doesn't burn as well as a low one. Haven't really read anything authoritative on the matter.
