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 ↓
Escaloped Potatoes
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
Preheat the oven to 350°F (175°C).
Slice the cold boiled potatoes very thin and season with salt and pepper.
Assemble
Butter a pudding dish and cover the bottom with a layer of cream sauce.
Add a layer of potatoes, sprinkle with chopped parsley, and moisten with sauce.
Repeat layers until all ingredients are used, finishing with a layer of sauce.
Top and bake
Top with bread crumbs, grated cheese, and 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
- Potatoes
- Form the bulk of the dish, giving it substance and a soft, tender body when baked.
- Cream sauce
- Moistens the potato layers and creates a rich, creamy texture as it heats.
- Bread crumbs
- Form a crisp, golden top layer that contrasts with the soft potatoes beneath.
- Butter
- Adds richness and helps the topping brown in the oven.
The step that matters
Finishing with a layer of sauce. Cooked potatoes absorb liquid slowly, so each layer needs enough sauce. Without it, the potatoes can stay dry and firm while the top browns too quickly.
