I bought one of those funnel cake kits for home use and it comes with a round metal ring to place in your electric skillet or panYou are supposed to fill oil up to the center line of the ring, but when I pour oil in, it mostly all just leaks out into the rest of the pan because the ring is not completely flush with the panI have tried flipping the ring over but that didn't helpHow do I keep the oil in the ring?
