Why it works: Pepper and mustard are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
Chop the cold roast or boiled chicken in a bowl.
Mix in the gravy and add minced hard-boiled eggs.
Season with salt and pepper to taste, then mix into a soft paste.

Spread the chicken mixture between the slices of bread.
If desired, add a little mustard before pressing the pieces gently together.
Arrange the sandwiches on a fringed napkin on a serving tray.
