Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the bulk of the filling and release juice as they cook.
- Flour
- Thickens the juices released by the tomatoes so the filling holds together.
- White sugar
- Adds sweetness and balances the acidity of the tomatoes.
- Pastry
- Forms the crust that encloses the filling and browns in the oven.
The step that matters
Thickening the juices with flour. Tomatoes release a lot of liquid as they bake. Flour gelatinises in that liquid and sets the filling; without enough of it, the pie can run and turn soggy.
Swap the tomato
How well each one fits the dish's main ingredients (lemon, sugar, flour):
- Arrowrootfits better
- Kalefits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against lemon, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
