Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Baked Potatoes with Anchovies
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
Peel, boil, and slice the potatoes.
Wash the anchovies, then remove the skin and bones.
Cut the hard-boiled eggs into quarters.
Butter a deep baking dish thickly.
Layer and bake
Layer 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 breadcrumbs and small pieces of butter.
Wipe the edges of the dish and bake at 400°F (200°C) for 15 minutes.

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 and soften into a tender, starchy base as they bake.
- Anchovies
- Add a salty, savoury depth that flavours the layers as they cook.
- Hard-boiled eggs
- Add a rich, creamy texture between the potato layers.
- Sour cream
- Adds moisture and tang, keeping the layers from drying out in the oven.
- Breadcrumbs
- Form a crisp, golden top layer as the dish bakes.
- Butter
- Adds fat that enriches the dish and helps the top brown.
The step that matters
Layer and bake. Moistening each potato layer with sour cream keeps the potatoes from drying out during baking. Wiping the dish edges keeps them from scorching or burning onto the dish.
