There is a festival vendor in my area who takes his equipment to carnivals and local fairs and high school fundraiser events and football games, where his booth is Kettle Corn.
He has 40-gallon kettles made of bronze. He has propane burners that he sets the kettles on, and throws in a measure of oil, then after it heats up, he pours in a bunch of popcorn kernels and stirs it up with a long wooden paddle. Then he covers the kettle for a minute and after the popping starts, he opens the kettle and stirs the kernels constantly, while the pile grows higher in the kettle. Finally he adds some caramel syrup, and keeps stirring, and I think he reduces the heat at some point.
So he goes through a lot of oil. And he sells a lot of kettle corn.
And I asked him what kind of oil it is, and he said, "Canola oil."
