Why it works: Mustard and watercress match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 293 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Ham En Panier
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.
Prepare the rolls
Cut a slice from each roll and scoop out the soft center.
Dry the bread shells in a 400°F (200°C) oven until slightly browned.
Make the filling
Mince the ham and 2 of the hard-cooked eggs, then heat them in the white sauce.
Add chopped parsley, pepper, coarse sea salt, and made mustard to the mixture.
Fill and serve
Fill the bread cases with the ham mixture.
Garnish with slices of the remaining egg and sprigs of watercress.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked ham
- Provides the main savory filling and meaty bulk of the dish.
- White sauce
- Binds the minced ham into a moist, creamy filling.
- Hard-cooked eggs
- Add body and richness to the filling, and their sliced whites and yolks make the garnish.
- Small rolls
- Form edible shells that hold the filling and crisp slightly when dried in the oven.
The step that matters
Drying the bread shells. Baking the empty shells until slightly browned firms the crumb and creates a barrier, so the hot, wet filling does not soften them into a soggy case.
Swap the parsley
How well each one fits the dish's main ingredients (ham, sauce, egg, pepper, mustard, watercress):
- Capersfits better
- Tarragonfits better
- Parsleythe original
- Celeryfits less well
Fit is the average pairing score against ham, sauce, egg, pepper, mustard, watercress. Candidates are from the same food group and used in at least 100 recipes.
