Why it works: Onion and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Timbale
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 oven to 350°F (175°C).
Beat eggs and egg whites together in a bowl.
Add salt, sugar, baking soda, onion juice, cream, and tomato puree to the egg mixture and mix until well combined.
Pour mixture into buttered timbale molds.
Bake and serve
Place molds in a baking dish surrounded by boiling water.
Bake until firm, ensuring the water does not boil after placing the molds in the oven.
Serve turned out from the molds with cream sauce.

Onion and cream barely smell alike, yet cooks put them together in 10,827 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
- Eggs
- Set into a firm custard structure as the mixture bakes.
- Egg whites
- Add extra protein for a firm, sliceable set.
- Cream
- Adds richness and a smooth, tender texture.
- Tomato puree
- Provides moisture, tomato flavour and mild acidity.
The step that matters
Keep the water bath below a boil. Gentle, indirect heat lets egg proteins set evenly. Boiling water overheats the edges, which can make the custard rubbery, porous or curdled.
Swap the tomato
How well each one fits the dish's main ingredients (egg, sugar, onion, cream):
- Leekfits better
- Chivefits better
- Potatofits better
- Tomatothe original
Fit is the average pairing score against egg, sugar, onion, cream. Candidates are from the same food group and used in at least 100 recipes.
