Why it works: Sage and lemon match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 887 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Roast Pig
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the pig
Kill and clean the pig the evening before or very early in the morning.
Scrape and wash the pig in cold water, changing the water two or three times.
Cut the feet off close to the first joint and place them with the heart and liver in a saucepan to stew.
Stuff and roast
Fill the body of the pig with mashed Irish potatoes seasoned with pepper, salt, butter, and lard.
Sew the body up and rub the outside with salt and pepper.
Roast the pig in a 400°F (200°C) oven, turning it often and rubbing it with lard tied in muslin to crisp the skin.
Cook the pig until golden brown and serve with a lemon, apple, or small orange in its mouth.
Make the sides
Chop the boiled feet, liver, and heart finely, season, and stew with sage leaves.
Thicken the drippings from the pig with flour, bring to a boil, and serve as gravy.
Prepare an alternative stuffing with scalded bread crumbs, seasoned with salt, pepper, butter, sage, and chopped onion.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig
- Is the main cooked meat; its skin crisps and its fat bastes the meat during roasting.
- Irish potatoes
- Fill the cavity, absorbing juices and fat so the stuffing stays moist and soft.
- Butter
- Adds fat and richness to the potato stuffing, carrying flavor and moisture.
- Lard
- Adds fat that helps the skin brown and crisp when rubbed on during roasting.
- Flour
- Thickens the pan drippings into a smooth gravy.
- Sage leaves
- Add a savory, aromatic herb flavor to the stewed offal and stuffing.
The step that matters
Roast the pig in a 400°F (200°C) oven, turning it often. Turning exposes all sides to heat so the thick body cooks evenly, while rubbing with fat helps the skin crisp and brown rather than stay soft or burn in patches.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, butter, sage, flour, lemon):

- Onionthe original
Fit is the average pairing score against potato, pepper, butter, sage, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
