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 with Peppers
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
Cut the potatoes into 1-inch cubes.
Layer half of the potatoes in a buttered baking dish.
Mix the minced onion, red pepper, green pepper, parsley, salt, and pepper.
Add a layer of the pepper mixture over the potatoes.
Repeat with the remaining potatoes and pepper mixture.
Assemble and bake
Pour the cream sauce over the layers.
Melt the butter.
Mix the melted butter with the bread crumbs, then sprinkle on top.
Bake at 400°F (200°C) for 25 minutes.
Serve hot.

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 become tender and soft when baked.
- Cream sauce
- Adds moisture and richness that coats the layers and keeps them from drying out.
- Bread crumbs
- Form a buttered topping that browns and adds a crisp contrast to the soft layers.
- Red pepper and green pepper
- Add sweetness, color and a fresh vegetable flavor between the potato layers.
The step that matters
Layering the potatoes and pepper mixture. Building even layers lets the cream sauce soak evenly through the potatoes while they bake, so the dish cooks uniformly and does not turn dry in some spots and watery in others.
Swap the onion
How well each one fits the dish's main ingredients (potato, cream, sauce, pepper, parsley, butter, bread):
