Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young pig
- Is the whole main dish, so its size and age set the roasting time and texture.
- Butter
- Basting fat that keeps the skin and meat moist while it browns and crisps.
- Flour
- Thickens the pan drippings into gravy.
- Baking soda
- Rinse water with baking soda is used to clean the skin of the pig.
- Onion
- Adds aroma and savory flavor to the dressing stuffed inside the pig.
The step that matters
Rub the skin with melted butter. Fat coats the skin so it can brown and crisp in the oven. Skin left dry or unbasted can turn tough and leathery during a long roast.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, pepper, wine, parsley, celery):
- Carrotfits better
- Shallotfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against butter, flour, pepper, wine, parsley, celery. Candidates are from the same food group and used in at least 100 recipes.
