Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whisked with sugar to give the filling structure and lift, setting as it bakes.
- Granulated sugar
- Sweetens the filling and helps the egg whites hold together and brown in the oven.
- Ground almonds
- Provide body, nutty flavour and moisture to the almond filling.
- Puff or short pastry
- Forms the crisp case and top layer that holds the filling in each tart.
The step that matters
Beat the sugar and egg whites until well combined. Sugar and egg whites need to be fully combined so the mixture sets evenly and does not separate or weep during baking. Uneven mixing can leave pockets of unset filling or uneven texture across the tarts.
Swap the almond
How well each one fits the dish's main ingredients (sugar, egg):
- Pecansfits about as well
- Almondthe original
- Chestnutfits about as well
- Milletfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
