Why it works: Tomato and parsley are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 5,398 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Steamed Eggs with Tomatoes
Ingredients
Directions
Prepare and steam the eggs
Butter 4 small dariole moulds and sprinkle the bottom of each with chopped parsley.
Carefully break an egg into each mould and place them in a saucepan with boiling water halfway up the sides.
Cover each mould with a piece of buttered paper and steam for about 5 minutes, or until set.
Cook the tomatoes and toast
While the eggs are cooking, cut the tomatoes in half and place them in a tin in a hot oven.
Add a small piece of butter on each tomato and cook until tender.
Toast the bread and bacon until crispy.
Assemble and serve
Once everything is cooked, trim the toast neatly and place half a tomato on each slice.
Carefully slip an egg onto each tomato and arrange on a dish with the slices of bacon.

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 yet tender custard when gently steamed, forming the dish's main structure.
- Tomatoes
- Add moisture and acidity, and soften and sweeten slightly when baked in butter.
- Bacon
- Adds savory fat and flavor, and browns and crisps when toasted.
- Butter
- Adds richness and flavor, and helps the tomatoes soften and brown.
- Toast
- Gives a crisp, absorbent base that holds the tomato and egg.
The step that matters
Steaming the eggs gently. Eggs cooked with too much heat or for too long turn rubbery and watery. Keeping the water below the rims and checking at about 5 minutes lets the proteins set softly.
Swap the tomato
How well each one fits the dish's main ingredients (egg, parsley, butter):
- Shallotfits better
- Chivefits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against egg, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
