Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mayonnaise
- Adds moisture and richness to the filling and helps the bread brown when brushed on the outside.
- Swiss cheese
- Melts to bind the fillings together and add a creamy, savoury layer.
- Bacon
- Adds salt, smoky flavour and crisp texture against the soft bread and melted cheese.
- Smoked turkey breast
- Provides the main savoury protein and meaty bulk of the sandwich.
- Sourdough bread
- Forms the crisp, browned outer structure that holds the filling together.
The step that matters
Browning the sandwiches in the pan. Medium heat and gentle pressure let the bread crisp and brown while the cheese melts through. Too high a heat scorches the outside before the cheese softens, and too little pressure leaves gaps and uneven browning.
