Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Escalloped Potatoes
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
Preheat the oven to 400°F (200°C).
Season the sliced potatoes with salt and pepper.
Butter a baking dish and cover the bottom with a layer of cream sauce.
Layer and bake
Add a layer of potatoes and sprinkle with chopped parsley.
Repeat layering with sauce and potatoes until the dish is filled.
Finish with cream sauce on top and sprinkle with bread crumbs mixed with small bits of butter.
Bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the bulk of the dish, becoming tender and soaking up the sauce as they bake.
- Cream sauce
- Supplies moisture and richness that keeps the layers creamy rather than dry.
- Bread crumbs
- Form a crisp, golden topping through browning in the oven.
- Butter
- Adds fat and richness, and helps the bread crumb topping brown.
The step that matters
Layering the sauce and potatoes. Enough cream sauce must reach between every layer, because cooked potatoes absorb liquid as they heat. Skimping on sauce leaves the dish dry and the potatoes firm rather than creamy.
Swap the potato
