Ingredients
Method
- Cook onions slowly 25–30 minutes, add sugar and vinegar for final 2 minutes.
- Shape mince into 4 patties.
- Season just before cooking.
- Sear 3 minutes, flip, cook 2–3 minutes more.
- Add Stilton in final minute, cover briefly to melt.
- Toast buttered buns.
- Build with lettuce, patty, onions and rocket.
Notes
Cook the onions low and slow for proper sweetness against the cheese.
Cover the pan briefly if the blue cheese needs extra help melting.
Raw patties freeze well for up to 3 months.
Caramelised onions freeze separately for up to 2 months.
