Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peanut butter
- Forms the creamy filling and provides rich, nutty flavour and fat.
- Egg
- Binds the coating so the bread takes on a golden, set crust when fried.
- Bread
- Holds the filling and fries to a crisp, browned exterior.
- Butter
- Adds fat for frying, promoting browning and a rich flavour on the bread.
The step that matters
Fry the sandwiches in butter until golden brown. Moderate heat lets the egg coating set and the bread brown evenly. Too hot and the outside browns before the egg cooks, while too cool and the sandwich becomes greasy and soggy.
Swap the parsley
How well each one fits the dish's main ingredients (peanut, butter, milk, bread, egg):
- Nutmegfits better
- Cinnamonfits better
- Parsleythe original
- Garlicfits about as well
Fit is the average pairing score against peanut, butter, milk, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
