Why it works: Tomato and potato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,798 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Pudding
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).
Butter a pie dish generously.
Layer and season
Layer sliced tomatoes at the bottom of the dish.
Add a layer of mashed potatoes on top.
Repeat the layers until the dish is full.
Season with pepper and salt.
Bake and finish
Beat the egg and pour it over the layers.
Sprinkle bread crumbs on top.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and moisture of the pudding as they soften during baking.
- Potatoes
- Add starch and body, helping the layers hold together as a soft, spoonable pudding.
- Egg
- Binds the layers as it sets in the oven, giving the pudding a custard-like structure.
- Bread crumbs
- Form a crisp, browned topping during baking.
- Butter
- Adds richness and helps the crumbs and dish surface brown.
The step that matters
Bake until golden brown. The egg needs to set fully while the top browns; underbaking leaves the pudding loose and wet in the centre, while overbaking can make it dry and tough.
