Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Prepare the bottom crust and place the sliced tomatoes in it.
Add the filling
Add vinegar, sugar, and butter to the tomatoes.
Sprinkle allspice and flour over the mixture.
Bake
Cover with the top crust and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Make up the bulk of the filling and provide its tart, fresh body.
- Vinegar
- Adds acidity that brightens the flavor and sharpens the tomatoes' tartness.
- Sugar
- Balances the vinegar's sharpness and adds sweetness to the filling.
- Butter
- Adds fat for richness and a softer mouthfeel in the baked filling.
- Flour
- Thickens the juices released by the tomatoes as the pie bakes.
The step that matters
Sprinkle the flour evenly over the tomatoes. Flour is a starch that thickens the juices as they heat. If it clumps or lands in one spot, some areas stay watery or pasty, so an even dusting lets the filling set uniformly.
Swap the tomato
How well each one fits the dish's main ingredients (vinegar, sugar, butter, allspice, flour):
- Mustardfits better
- Shallotfits better
- Arrowrootfits better
- Tomatothe original
Fit is the average pairing score against vinegar, sugar, butter, allspice, flour. Candidates are from the same food group and used in at least 100 recipes.
