Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when cooked, binding the onions and chillies into a soft, cohesive filling.
- Stale bread
- Provides the structure that holds the filling, and stale slices absorb less moisture so they stay firm.
- Milk
- Thins the egg mixture, giving it a softer, more tender texture as it sets.
- Butter
- Adds fat and richness to the bread, promoting browning and flavour.
- Onions
- Add sweetness and savoury depth when browned in ghee.
The step that matters
Cook the egg mixture until just set. Eggs turn firm and rubbery when overcooked, and they keep cooking from residual heat. Removing the pan while the mixture is still slightly soft keeps the filling tender.
