Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
A Giblet Pie
Ingredients
Directions
Make the stock
In a saucepan, combine giblets (except livers), water, peppercorns, mace, sweet herbs, and onion.
Cover and simmer until tender.
Assemble and bake
Prepare a crust and place the rump steak at the bottom, seasoned with salt and pepper.
Add the giblets and livers, then strain the cooking liquid over them.
Season the liquid with salt and pepper, pour it into the pie, cover with the lid, and bake for 1.5 hours.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Giblets
- Provide the main savoury flavour and body for the pie filling as they simmer.
- Rump steak
- Adds meaty substance and richness that the stock-based filling surrounds.
- Onion
- Contributes aromatic sweetness and depth to the cooking liquid as it simmers.
- Puff pastry crust
- Forms a flaky, golden enclosure that holds the filling and browns in the oven.
The step that matters
Simmering the giblets until tender. Giblets need a long, gentle simmer to break down connective tissue. Rushing this leaves them tough, and a rapid boil can cloud the liquid and toughen the meat.
Swap the mace
How well each one fits the dish's main ingredients (onion, pepper):
- Garlicfits better
- Thymefits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
