Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onions: Form the main body of the rings and, once cooked, provide sweetness and tender texture.
Eggs: Bind the milk soak and help the pancake mix coating adhere to the onion rings.
Milk: Moistens the eggs and soaks into the onions, helping the coating stick evenly.
Powdered pancake mix: Forms the crisp, golden coating that browns when the rings are fried.

The step that matters

Deep-fry rings in 375°F (190°C) oil until golden brown. Oil that is too cool lets the coating soak up grease and turn heavy, while oil at the right heat sets the batter quickly into a crisp shell. Frying until golden brown gives flavour from browning and cooks the onion through.
