What each ingredient does
- Onions
- Provide sweetness and body to the filling as they slowly caramelise to light brown.
- Sweet lard
- Adds fat and moisture, carrying the onions' flavour and keeping the filling tender.
- Pig's leaf
- Supplies rich leaf fat that melts into the filling, adding moisture and a soft texture.
The step that matters
Stew the mixture slowly until the onions are light brown. Cooking onions gently lets their natural sugars break down and brown slowly, building sweetness and depth. Rushing over high heat can scorch them, leaving bitterness and uneven colour.
