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 the pig.
Clean the pig.
Scrape the pig.
Wash the pig in cold water, changing the water two or three times.
Cut the feet off close to the first joint.
Place the feet 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.
Rub the outside of the pig with salt and pepper.
Roast the pig in a 400°F (200°C) oven.
Turn the pig often.
Rub the pig with lard tied in muslin to crisp the skin.
Make the gravy and stuffing
Chop the boiled feet, liver, and heart finely.
Season the chopped meat.
Thicken the meat with butter and flour.
Serve the drippings from the pig as gravy.
Prepare an alternative stuffing.
Scald bread crumbs.
Season the stuffing with salt, pepper, butter, sage, and chopped onion.
Garnish the pig with a lemon, apple, or small orange in its mouth before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole pig
- Forms the main meat that is roasted whole and carved for serving.
- Irish potatoes
- Fill the body with a moist, starchy stuffing that absorbs roasting juices.
- Lard
- Adds fat that helps crisp the skin and carries flavor across the surface.
- Butter
- Adds richness and flavor to the stuffing and the thickened meat.
- Flour
- Thickens the chopped meat and drippings into a smooth gravy.
The step that matters
Turn the pig often. Frequent turning exposes all sides to the oven's heat so the meat cooks evenly and the skin browns rather than scorching in one spot.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, butter, sage, flour, lemon):
- Chivefits better
- Shallotfits better
- Spinachfits better
- 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.
