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 ↓
Roast Pig
Ingredients
Directions
Prepare
Prepare dressing as for "Dressing for Fowls," adding chopped onion.
Wash the pig inside and out, then rinse with water mixed with baking soda.
Dry the pig with a fresh towel, salt the inside, and stuff it with the dressing.
Sew it up and place it in a kneeling position in a dripping pan, tying the legs.
Roast
Pour a little hot salted water into the pan and baste with butter and water as it warms.
When it begins to smoke, rub it with a rag dipped in melted butter to keep the skin crisp.
Roast for 2 to 3 hours, basting occasionally.
Make gravy and serve
Make gravy by skimming off grease, stirring in flour, and adding water to desired consistency.
Season with pepper and boil once, then strain and add wine if desired.
Serve the pig on a large hot platter, garnished with parsley or celery tops, and decorate with a wreath and celery.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig
- Provides the main meat, which cooks through slowly while the skin crisps.
- Butter
- Adds fat that bastes the skin, promoting browning and a crisp, rich surface.
- Baking soda
- Rinse water with baking soda is meant to help the skin brown and crisp during roasting.
- Flour
- Thickens the gravy as it is stirred into the skimmed pan juices.
- Onion
- Adds savory aroma and flavor to the dressing stuffed inside the pig.
The step that matters
Rubbing the skin with melted butter once it starts to smoke. Fat helps the skin brown and crisp rather than dry out or toughen. Applying it at the right moment, when the skin is hot, lets it crisp evenly while the meat cooks through.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, pepper, wine, parsley, celery):
