Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Stuffed Eggs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Boil and shell
Boil the eggs for 20 minutes.
Plunge them into cold water for 1 minute.
Remove the shells and cut the eggs lengthwise.
Scoop out the yolks carefully and place the whites together.
Make and fill
Mash the yolks and mix with ham, onion juice, melted butter, cayenne, celery salt, and parsley.
Fill the egg whites with the yolk mixture and press the halves together.
Spread the remaining mixture on a buttered dish and place the eggs on top.
Bake
Cover with thin white sauce, sprinkle with buttered cracker crumbs and cheese.
Bake at 400°F (200°C) until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites set to hold the filling, and the yolks form the rich, creamy filling.
- Ham
- Adds savoury, salty flavour to the yolk mixture.
- Butter
- Adds richness and moisture to the yolk filling and helps the topping brown.
- White sauce
- Adds moisture and a smooth, creamy coating over the eggs as they bake.
- Cracker crumbs
- Form a crisp, golden-brown topping in the oven.
- Cheese
- Melts and browns on top, adding savoury flavour.
The step that matters
Plunge the boiled eggs into cold water. Cold water stops the cooking right away, so the yolks stay tender and do not develop a dull grey-green ring. Cooling also makes the shells easier to remove cleanly.
Swap the onion
How well each one fits the dish's main ingredients (egg, ham, butter, pepper, celery, parsley, cheese):
- Carrotfits better
- Mustardfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against egg, ham, butter, pepper, celery, parsley, cheese. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
