What each ingredient does
- Tomatoes
- Provide the main body and moisture that softens and browns in the hot fat.
- Onion
- Adds sweetness and savory depth as it softens and caramelizes in the fat.
- Lard
- Conducts heat for frying and adds richness and browning to the surfaces.
The step that matters
Fry in hot lard until golden brown. The lard must be hot before the slices go in, otherwise the tomatoes and onions absorb fat and steam instead of searing. Good contact with hot fat drives browning and gives a crisp golden surface.
