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

What each ingredient does

Gluten-free flour

Forms the coating that crisps and browns around the onion when fried.

Egg

Binds the flour and milk into a batter that clings to the onion.

Milk

Adds moisture so the flour hydrates into a thin, spreadable batter.

Gluten-free baking powder

Releases gas that lightens the batter, giving a puffier, less dense coating.

Onion

Softens and turns sweet and aromatic as it cooks inside the crisp coating.
