Why it works: Mustard and onion match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stuffed Eggs
Ingredients
Directions
Prepare the filling
Cut the hard-boiled eggs in half lengthwise without breaking the whites.
Scoop out the yolks and mash them into a paste.
Moisten the yolks with melted butter, olive oil, gravy, cream sauce, stock, or a raw egg.
Add an equal amount of minced meat, fish, cheese, truffles, or mushrooms to the yolk paste.
Season the mixture with salt, pepper, mustard, onion, and curry powder to taste.
Mix everything well together and fill the egg whites with the mixture.
Assemble and serve
Press the egg whites together; you can scoop out more to hold extra filling.
If there's leftover filling, cover the eggs, roll them in raw egg, and coat with breadcrumbs before frying.
Serve the stuffed eggs hot with various sauces or cold with lettuce and dressing as a salad.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the white shells that hold the filling and the yolks that form the base paste.
- Egg yolks
- Mashed into a paste that gives the filling its rich, creamy body.
- Melted butter
- Adds fat and moisture so the yolk paste becomes smooth and rich.
- Olive oil or gravy
- Moistens the yolk paste, adding fat or savory liquid for a softer texture.
- Minced meat, fish, cheese, truffles, or mushrooms
- Supplies the savory, bulky filling that gives the stuffing its main flavor.
