The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Onions
- Provide the main body and sweet flavour of the rings once cooked and fried.
- Flour
- Coats the rings so the surface dries and crisps and browns during frying.
The step that matters
Fry the onion rings in a wire frying basket until crisp and golden brown. Fat must be hot enough that the coating dries and browns quickly. If the rings are added to fat that is too cool, they absorb more oil and turn greasy rather than crisp.
