Why it works: Olive and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 29,779 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ingredients
Directions
Prepare
Trim the pork, leaving only ½ inch of fat.
Place the pork in a pan.
Pour the olive oil over the pork.
Sprinkle salt and pepper over the meat.

A 4 lb piece will take 2 hours; a 2 lb piece will take 1½ hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork
- Forms the main body of the dish, and its fat renders and crisps into crackling during roasting.
- Olive oil
- Soaks into the meat during the long rest and, basted back over it, keeps the surface moist while roasting.
- Onions
- Sit with the pork during the soak, flavouring the oil that is later basted over the meat.
- Herbs
- Sit with the pork during the soak, infusing the oil with aroma that carries into the meat.
The step that matters
Score the fat for crackling. Scoring cuts through the fat layer so it can render and crisp evenly, while the lean meat stays protected below. Shallow, even cuts give the best crackling.
Swap the onion
How well each one fits the dish's main ingredients (pork, olive, pepper):
- Capsicumfits better
- Tomatofits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against pork, olive, pepper. Candidates are from the same food group and used in at least 100 recipes.
