Why it works: Egg and butter match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and 118,511 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into soft curds that form the main body of the dish.
- Stewed and strained tomatoes
- Add moisture and acidity, blending into the eggs as they cook.
- Butter
- Adds richness and fat, helping the eggs cook gently without sticking.

Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
