What each ingredient does
- Tomatoes
- Hollowed out to hold the filling; their flesh gives moisture and a fresh acidity.
- Cooked chicken
- Provides the protein and bulk of the filling.
- Hard boiled egg yolks
- Add richness and a creamy, crumbly texture to the filling.
- Mayonnaise dressing
- Binds the filling together and adds fat for a smooth, moist texture.
- Celery seed
- Adds a savoury, aromatic flavour that suits the chicken and egg.
