Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Tomato Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Skin and slice the ripe tomatoes.
Sprinkle the tomatoes with salt and sugar.
Make the filling
In a bowl, mix the cream and egg together.
Pour the cream mixture over the tomatoes.
Bake
Cover with a rich pie crust.
Bake until the crust is golden and the filling is set.

Cream and egg barely smell alike, yet cooks put them together in 42,166 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Form the main filling and release juice that moistens the pie as it cooks.
- Cream
- Adds richness and a silky texture to the filling.
- Egg
- Sets the cream mixture so the filling firms when baked.
The step that matters
Bake until the filling is set. Egg proteins coagulate as they heat, firming the cream custard. Pulling the pie too early leaves a runny filling, while overbaking can make it grainy or cause it to weep.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, cream, egg):
- Leekfits better
- Sweet potatofits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against sugar, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
