Why it works: Onion and potato 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 ↓
Meat Scallop
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.
Make the meat filling
In a saucepan, melt the butter and sauté the minced onion until hot.
Add the flour and stir until smooth, then gradually add the hot water, seasoning to taste.
Mix in the chopped cold meat until well combined.
Top and bake
Transfer the mixture to a baking dish and cover with a layer of seasoned mashed potatoes.
Wet the potatoes with a little milk and optionally mix in the beaten egg white for better texture.
Bake at 400°F (200°C) for 20 minutes or until the top is light brown.
Serve
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the hot water into a smooth, cohesive filling that holds the meat together.
- Butter
- Adds fat and flavour to the onion and helps the filling feel rich.
- Egg white
- Optionally beaten in to help the potato topping set and improve its texture.
- Cold meat
- Forms the main body of the filling, held together by the thickened sauce.
The step that matters
Thickening the flour with hot water. Flour must be stirred smooth before the hot water is added gradually; adding it all at once can leave lumps, because flour starch needs to be dispersed before it thickens.
Swap the onion
