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 Omelette
Ingredients
Directions
Make the tomato base
Stew the chopped tomatoes for 10 minutes with onion juice, salt, pepper, and rolled cracker.
Remove the tomatoes from heat and let cool slightly.
Make the omelette
Beat the eggs very light, separating the yolks and whites.
Stir in the yolks thoroughly.
Gently fold in the egg whites.
Pour the mixture into a hot frying pan with melted butter.
Reduce the heat to low and cook until the omelette rises and is lightly browned on the bottom.
Fold the omelette.
Serve
Serve on a hot dish garnished with triangular pieces of toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift and the yolks add richness and set the omelette.
- Canned tomatoes
- Provide moisture and acidity that give the omelette its flavour and filling.
- Soda cracker
- Its starch thickens the stewed tomatoes so they hold together in the omelette.
- Butter
- Adds fat for flavour and helps the bottom brown in the pan.
The step that matters
Folding the egg whites. Whites hold air only when whipped and folded gently; stirring or deflating them makes the omelette flat and dense instead of rising.
Swap the tomato
How well each one fits the dish's main ingredients (onion, pepper, egg, butter):
