Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and moisture, and its molasses gives the filling a caramel flavour.
- Peanuts or almonds
- Add crunch and a nutty flavour to the sugar filling.
- White bread
- Provides the soft structure that holds the filling.
- Butter
- Adds richness and fat that keeps the bread from soaking up the filling.
The step that matters
Chop the nuts very finely. Fine pieces spread evenly through the sugar and stay in the sandwich without tearing the soft bread. Large pieces can poke through and make the filling hard to bite through.
Swap the peanut
How well each one fits the dish's main ingredients (sugar, bread, butter):
- Almondfits better
- Pecansfits better
- Lima beansfits better
- Peanutthe original
Fit is the average pairing score against sugar, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
