Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Baked Potatoes with Anchovies
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Peel, boil, and slice the potatoes.
Season the potatoes with coarse sea salt.
Wash the anchovies, then remove the skin and bones.
Cut the hard-boiled eggs into quarters.
Butter a deep baking dish thickly.
Assemble
Layer the sliced potatoes in the bottom and moisten with sour cream.
Add a layer of eggs and anchovies, alternating until the dish is full.
Finish with a layer of potatoes on top, moisten with sour cream, and sprinkle with bread crumbs and a small piece of butter.
Bake
Wipe off the edges and bake for 15 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish, becoming soft and creamy as they bake.
- Anchovies
- Add a salty, savory depth that seasons the layers from within.
- Hard-boiled eggs
- Add a soft, rich texture that contrasts with the potatoes and fish.
- Sour cream
- Adds moisture and tang, keeping the layers from drying out in the oven.
- Bread crumbs
- Form a crisp, golden topping as they brown in the oven.
- Butter
- Adds richness and helps the top crumbs brown.
The step that matters
Moisten each layer with sour cream. Potatoes absorb liquid as they bake, and without enough sour cream between layers the dish can turn dry and dense rather than moist and creamy.
Swap the potato
How well each one fits the dish's main ingredients (egg, cream, bread, butter):
- Leekfits about as well
- Asparagusfits about as well
- Potatothe original
- Chivefits about as well
Fit is the average pairing score against egg, cream, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
