Why it works: Tomato and lemon are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,592 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Old-fashioned Green Tomato Pie
3 piesIngredients
Directions
Prepare the tomatoes
Cut the green tomatoes into pieces the size of a nutmeg before measuring.
In a pot, combine tomatoes, water, brown sugar, and salt. Cook the mixture slowly for a full day.
The next day, drain off all the juice.
Make the filling
Heat the drained mixture.
Thicken the mixture with flour until it reaches gravy consistency.
Flavor the mixture strongly with extract of lemon.
Add the cooked tomatoes to the mixture and let it cool.
Assemble and bake
Prepare 3 pies using 2 crusts each.
Dot the top crust with bits of butter before baking.
Wait until the next day to bake the pies.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the filling and supply its tart, fruity body.
- Brown sugar
- Sweetens the filling and draws moisture out of the tomatoes during the long cook.
- Flour
- Thickens the released juices into a gravy-like filling that holds its shape when sliced.
- Butter
- Adds richness and fat, melting over the top crust to aid browning and flavor.
- Lemon extract
- Adds a bright citrus aroma that offsets the sweetness of the filling.
The step that matters
Thicken the mixture with flour. Flour only thickens when it is heated in the liquid and mixed in evenly, so stir it in fully to avoid lumps and a filling that stays runny or pasty.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, lemon, butter, flour):
- Arrowrootfits better
- Shallotfits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against sugar, lemon, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
