Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. 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 the potatoes
Peel and steam the potatoes until done.
Slice the potatoes as you would for frying.
Layer and bake
Butter an earthen dish and layer the sliced potatoes.
Season each layer with salt, pepper, butter, and chopped onion.
Sprinkle a little flour over each layer.
Continue layering until the dish is filled.
Let the dish stand for 30 minutes.
Pour 1 cup of milk over the top.
Bake at 350°F (175°C) for 35 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, becoming tender as they cook through in the oven.
- Flour
- Thickens the milk into a sauce that binds the potato layers together.
- Milk
- Forms the creamy liquid that cooks with the potatoes and flour into a sauce.
- Butter
- Adds richness and flavor and helps the top brown in the oven.
- Onion
- Adds savory aroma and flavor that spreads through the layers as it bakes.
The step that matters
Pour the milk over the top. Milk added before flour and butter are evenly distributed can leave lumps or pooled liquid. Flour thickens the milk as it heats, so the layers need to be sprinkled evenly to form a smooth, cohesive sauce.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, pepper, flour, milk):
- Chivefits better
- Capsicumfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against potato, butter, pepper, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
