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 ↓
Scalloped Vegetables
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a baking dish, layer the cooked vegetables.
Bake and serve
Dot the top with butter and sprinkle with salt and pepper.
Bake for 20-30 minutes until heated through and slightly golden on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk of the dish and a soft, starchy body once heated.
- Onions
- Add savory sweetness and aroma as they warm in the baking dish.
- Cauliflower
- Adds mild flavor and a tender texture to the layered vegetables.
- Butter
- Adds richness and moisture, and helps the top turn golden as it bakes.
The step that matters
Bake until heated through and lightly golden. Vegetables are already cooked, so the bake mainly heats them evenly. Baking past the golden stage can dry the top and the butter can brown too quickly, so watch the surface rather than relying only on the time range.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, onion, cauliflower, butter):
- Garlicfits better
- Capersfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against potato, onion, cauliflower, butter. Candidates are from the same food group and used in at least 100 recipes.
