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 ↓

Ingredients
Directions
Make the crust
In a bowl, mix flour, baking powder, and salt.
Rub in the pork fat or lard until crumbly.
Gradually add water to form a smooth paste.
Line a deep pudding dish with the crust.
Layer and seal
Layer sliced onions, potatoes, and pork in the dish, repeating until full.
Wet the edges of the crust and cover with a top crust.
Tie a floured cloth over the top and place in a pot of boiling water.
Boil and serve
Ensure the water covers two-thirds of the dish and boil for four hours.
Invert onto a serving dish, remove the mold, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the dough structure that holds the filling together as it cooks.
- Baking powder
- Releases gas during cooking, helping the crust rise and stay light.
- Pork fat or lard
- Rubbed into the flour to make the crust short and tender.
- Water
- Hydrates the flour to form a smooth, workable paste for the crust.
- Pork
- Provides the main meat filling, releasing juices that flavor the potatoes and onions.
The step that matters
Ensure the water covers two-thirds of the dish and boil for four hours.. If the water level drops or the boil is weak, the crust and filling cook unevenly and the crust may turn soggy. Steady, sustained boiling heats the dish and cooks the pork through.
Swap the onion
