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 the pig
Prepare dressing as for fowl, adding chopped onion.
Set the dressing aside.
Dissolve baking soda in separate water.
Rinse the inside of the pig again.
Wipe the pig dry with a fresh towel.
Salt the inside of the pig.
Stuff the pig with the prepared dressing.
Sew the pig up.
Roast
Place the pig in a kneeling position in a dripping pan, tying the legs properly.
Pour a little hot salted water into the dripping pan.
Baste the pig with a mixture of butter and water as it warms.
Baste the pig with gravy from the pan.
When the pig begins to smoke, rub it often with a rag dipped in melted butter to keep the skin crisp.
Roast for 2 to 3 hours.
Make the gravy
Skim off most grease from the pan.
Stir in flour.
Add water to achieve the right consistency.
Season with pepper.
Let the gravy boil once.
Strain the gravy.
Add wine if desired.
Serve the gravy in a gravy boat.
Serve and carve
Place the pig on a large, hot platter, garnished with parsley or celery tops, a green wreath around the neck, and a sprig of celery in its mouth.
Cut off the head first.
Split down the back.
Remove hams and shoulders.
Separate the ribs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig
- Supplies the meat and fat that roast, render and become tender over the long cooking.
- Butter
- Adds fat that helps the skin brown and crisp and keeps it from drying out.
- Flour
- Thickens the gravy as its starch swells in the hot liquid.
- Onion
- Adds savory aroma to the dressing that flavors the stuffing.
- Wine
- Adds acidity and depth to the gravy, if used.
The step that matters
Rubbing the skin with buttered rag once it smokes. Surface fat and moisture help the skin brown and crisp evenly. Letting the skin dry out or go unfatted can leave it leathery, while too much heat without fat can scorch it.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, pepper, wine, parsley, celery):
