I once asked a restaurant (Au Coeval in Chicago) what kind of fat they use to fry their foods - to prove a point to a family member - and of course, they happened to use beef tallow so I promptly ordered multiple orders of french fries.

But on numerous occasions, I’ll ask and the result will be “a mix of canola and soybean oil” and my response is almost always “Oh wow, amazing!” as I promptly walk out and never come back.
