Baked in a sauce made with ketchup and lemon.
I’m curious why it specifies cooking oil, which isn’t a historical term of art, as far as I can tell. In other words, cooking oil means edible oil you can cook with. I don’t know what you think I was tempted to use, recipe box, but I assure you my culinary ambitions rarely involve Quaker State.
From a box sold in Chicago, Illinois.

1 T. lemon juice
