Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young pig
- Provides the main meat, which is roasted whole and stuffed.
- Butter
- Adds fat that bastes the skin and helps it brown and crisp.
- Flour
- Thickens the pan drippings into gravy.
- Baking soda
- Rinses the pig to help loosen the surface before drying.
- Onion
- Adds savory aroma and flavour to the stuffing dressing.
The step that matters
Rub the skin with melted butter when the pig begins to smoke. Fat applied as the skin heats helps it crisp and brown evenly. Skin that is left dry or unbasted can turn leathery while the meat cooks.
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.
