Why it works: Mustard and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 624 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Ham Sandwiches
Ingredients
Directions
Make the meat filling
Chop the meat finely, pound, and mix well in a bowl. Alternatively, use a food chopper.
Season the mixture with mustard, salt, paprika, and capers. Moisten with mayonnaise.
Chop the whites of the hard boiled eggs finely and mix them into the meat mixture.
Make the egg filling
Press the yolks of the hard boiled eggs through a sieve, season with salt and paprika, and mix with enough mayonnaise to spread.
Assemble and pack
Cream the butter and spread it on thin slices of bread.
On one slice, spread the meat mixture; on the other, spread the egg mixture.
Press the slices together, wrap in oiled paper, and pack. Ensure the sandwiches are moist.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled or baked ham
- Provides the main meaty body and savory flavor of the filling.
- Cold chicken
- Adds tender meat texture and mild flavor to the filling.
- Cold boiled tongue
- Contributes rich, tender meat texture and savory depth to the filling.
- Hard boiled eggs
- Give the egg filling its creamy, rich texture from the yolks and body from the whites.
- Mayonnaise
- Adds fat and moisture so the meat and egg mixtures spread and stay moist.
- Butter
- Adds fat and flavor to the bread and helps keep it from soaking up moisture.
The step that matters
Moistening the fillings with mayonnaise. Cold cooked meat and egg are dry and crumble easily. Adding just enough mayonnaise binds the filling and keeps it spreadable without making it soggy, which also helps the bread stay intact.
