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 ↓
Sea Pie
Ingredients
Directions
Make the dough
In a bowl, mix the flour, baking powder, and salt.
Rub in the pork fat until well combined.
Gradually add water to form a smooth paste.
Assemble
Line a deep pudding dish with the dough.
Layer in sliced onions, then potatoes, followed by sliced pork, and repeat until the dish is full.
Wet the edges of the crust and place a top crust over the filling.
Tie a floured cloth over the top and place the dish in a pot of boiling water.
Boil and serve
Ensure the water comes up two-thirds of the way up the dish and boil for four hours.
Invert the dish onto a plate, 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 encloses the filling and holds its shape.
- Baking powder
- Produces gas that lightens the crust so it rises slightly rather than staying dense.
- Pork fat or lard
- Shortens the dough, giving a tender, crumbly texture and adding richness.
- Potatoes
- Add starch and body to the filling, turning soft and absorbent during the long boil.
- Pork
- Supplies the main savory flavour and fat that drips into the filling during cooking.
The step that matters
Keeping the water level at two-thirds of the dish. If the water is too low, the top of the pudding cooks less evenly and the crust may dry out, while water that rises over the cloth can soak the pudding and make it soggy. Steady gentle boiling keeps the steam and heat even through the long cook.
Swap the onion
How well each one fits the dish's main ingredients (flour, pork, potato):

Fit is the average pairing score against flour, pork, potato. Candidates are from the same food group and used in at least 100 recipes.
