Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Barbecued Eggs and Ham
Ingredients
Directions
Prepare the ham mixture
Heat the butter in a skillet.
Fry the grated onion in the butter until fragrant.
Combine the minced ham, pepper, salad oil, and vinegar in a bowl. Let the mixture stand covered for 2 hours in a cool place.
Cook and serve
Stir the ham mixture into the skillet and cook, stirring constantly, until hot throughout.
Add the beaten eggs and cook until just set, but not hard.
Serve the mixture on buttered toast moistened with a little stock.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when heated to bind the mixture into a soft, tender curd.
- Cold boiled ham
- Provides savoury meat flavour and body to the egg mixture.
- Butter
- Adds richness and flavour to the onion and the pan.
- Vinegar
- Adds a sharp acidity that brightens the rich ham and egg.
The step that matters
Cooking the eggs until just set, but not hard. Eggs turn tough and rubbery when overcooked, because the proteins tighten and squeeze out water. Removing them while still soft keeps the texture moist and tender.
Swap the onion
How well each one fits the dish's main ingredients (butter, ham, pepper, vinegar, egg):
- Capsicumfits better
