What each ingredient does
- Haricot beans
- Form the main body of the dish and absorb the flavour of the bacon and onion.
- Brown bacon
- Adds savoury, smoky flavour and fat as it browns in the pan.
- Fat
- Carries heat into the bacon so it browns, and adds richness to the stew.
- Onion
- Adds aromatic sweetness and depth as it softens in the stew.
The step that matters
Browning the bacon. Browning the drained bacon in hot fat builds savoury flavour through the Maillard reaction. If the bacon is crowded or wet, it steams instead and the stew tastes flat.
