What each ingredient does
- Onions
- Form the main body; their sugars brown during frying, adding sweetness and colour.
- Flour
- Forms a thin dry coating that browns and crisps in the hot fat.
- Lard
- Conducts heat evenly to cook and brown the onion rings quickly.
The step that matters
Fry in hot lard until nicely coloured. The fat must be hot enough to crisp the flour coating quickly; if it is too cool, the rings soak up grease and turn soggy, and if too hot, the outside burns before the onion softens inside.
