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 ↓
Columbus Eggs
Ingredients
Directions
Peel the shells from the hard-boiled eggs and cut each egg in half.
Trim a small piece from one end of each half so they can stand upright.
Pulverize the yolks and mix with the minced meat.
Moisten the mixture with butter or vinegar and season with salt, pepper, and mustard.
Fill the egg whites with the mixture, pressing the halves together.
Place the filled eggs on a platter to resemble whole eggs.
For extra filling, add vinegar to the remaining mixture and pour it over the eggs.
