What each ingredient does
- Potatoes
- Form the bulk of the dish, providing starch that gives a soft, tender texture.
- Lard
- Fat that fries the onions, carrying flavour and helping them brown.
- Onions
- Soften and turn golden when fried, adding sweetness and savoury depth.
The step that matters
Fry the onions until golden brown. Onions cooked slowly in fat develop sweetness and colour through browning. Burning them turns them bitter, while pale onions leave the dish flat.
