Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Custard
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
Stew down and strain the canned tomatoes to measure 1 pint.
In a bowl, beat the eggs well and mix in the strained tomatoes, onion juice, salt, and pepper.
Grease custard cups with butter and fill them with the mixture.
Cook and serve
Steam or bake at 350°F (175°C) until set in the center.
Serve with cream sauce.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a firm, sliceable texture as they cook.
- Canned tomatoes
- Provide the main body, moisture, and tangy flavor of the custard.
The step that matters
Cook until set in the center. Eggs thicken as their proteins coagulate with heat. Pulling the custard once the center is just set keeps it tender and smooth; overcooking makes it rubbery and may cause it to weep or curdle.
Swap the tomato
How well each one fits the dish's main ingredients (egg, onion, pepper, butter, cream, sauce):
- Potatofits better
- Chivefits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against egg, onion, pepper, butter, cream, sauce. Candidates are from the same food group and used in at least 100 recipes.
