I was bemused to find "Gentile" olive oil from Bertolli on the Ocado website. I don't think foods should be ethnically segregated and I'm sure Nigella frequently slaps a bit of extra virgin in her recipes.
It reminds me of a bizarre, true-life incident back in the 1980s. My grandmother had died and my father was trying to make the funeral arrangements, but couldn't get hold of the elusive rabbi who was due to conduct the ceremony. Eventually, he tracked down a number and called very late at night. Unfortunately, it was the wrong number.
"Is that Rabbi Goldberg?" asked my father tentatively.
"No," came the sleepy and slightly irritated reply. "It's just some horrible gentile."
