Tomato Pie

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Remove the skins from the tomatoes and slice them thin.

  2. Place the sliced tomatoes into the pie crust.

  3. Add sugar, butter, vinegar, and flour to the tomatoes.

  4. Put strips of pie crust across the top.

Bake

  1. Bake at 300°F (150°C) until thoroughly done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Yellow tomatoes
Provide the main filling, releasing juice as they cook to make the body of the pie.
Sugar
Adds sweetness and balances the acidity of the tomatoes.
Flour
Thickens the juices released by the tomatoes so the filling sets rather than running.
Vinegar
Adds acidity that brightens the flavor of the tomatoes.
Butter
Adds richness and fat that carries flavor and softens the filling.

The step that matters

Bake until thoroughly done. Sliced tomatoes release a lot of liquid, and the flour only thickens it when the filling is fully heated. Underbaking leaves the filling runny and the crust soggy.

Swap the tomato

How well each one fits the dish's main ingredients (sugar, butter, vinegar, flour):

  1. Shallotfits better
  2. Mustardfits better
  3. Arrowrootfits better
  4. Tomatothe original

Fit is the average pairing score against sugar, butter, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
