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 in the steps was added when the recipe was transcribed, as a starting point.
Prepare the pig
Kill the pig.
Clean the pig.
Scrape and 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, 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 with salt and pepper.
Roast the pig in a hot oven (400°F / 200°C).
Turn the pig often.
Rub the pig with lard tied in muslin to crisp the skin.
Make the gravy and stuffing
Chop the feet, liver, and heart finely.
Boil them in clear water with sage leaves, then season highly.
Thicken the drippings with flour.
Boil the thickened drippings.
Serve as gravy.
Mix scalded bread crumbs with salt, pepper, butter, sage, and chopped onion for alternative stuffing.
Mix cornmeal with egg yolks and seasonings.
Bake the mixture in cakes.
Use the cakes as stuffing.
Serve
Serve the pig with a lemon or small orange in its mouth.

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 slowly until tender with crisp skin.
- Irish potatoes
- Fill the cavity, adding moisture and a soft, starchy texture to the stuffing.
- Lard
- Adds fat that helps the skin crisp and brown during roasting.
- Flour
- Thickens the pan drippings into a smooth gravy.
- Egg yolks
- Bind the cornmeal mixture so it holds together when baked into cakes.
- Cornmeal
- Forms the body of the baked stuffing cakes, giving them a grainy texture.
The step that matters
Turn the pig often. Uneven heat can scorch one side while the rest stays underdone. Frequent turning lets the fat render and the skin brown evenly.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, pepper, sage, flour, egg, lemon):
- Chivefits better
- Spinachfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, butter, pepper, sage, flour, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
