That’s the call made before kerosene, yes, kerosene gets thrown on an open fire. The subsequent fireball is the last hurrah before dinner is served.
When boiled, fish give off their oils, which float to the top of the water. This oil doesn’t taste very good, so you really want to remove it.
Fish isn’t particularly appetizing when overcooked, so it can’t take very long to skim that oil off the top. But how? That’s where the kerosene comes in. When the fish, potatoes, and onions are done cooking, a little bit of kerosene is flung onto the open flames. The sudden increase in heat causes the water to boil over and the oil on the top flows down the outside of the kettle.
Come and get it!
