Why it works: Egg and ham are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 4,526 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

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

Mash the potatoes until smooth.
Shape and bake
Form the mashed potatoes into balls.
Brush the balls with the egg yolk.
Bake in a 400°F (200°C) oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the starchy base that mashes smooth and holds the balls together.
- Egg yolk
- Adds richness and promotes browning on the surface during baking.
The step that matters
Brush the balls with the egg yolk. An even, thin coat of egg yolk gives a uniform golden colour in the oven. Uneven or thick coating can cause patchy browning or pooling.
Swap the potato
How well each one fits the dish's main ingredients (egg, ham):
- Asparagusfits better
- Mustardfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, ham. 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.
