Why it works: Pepper and sage match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 5,388 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
To Roast a Sucking Pig
Ingredients
Directions
Prepare the pig
Make the stuffing by mixing hot mashed potatoes with butter, mashed onions, sage, salt, and pepper.
Wash the pig in cold water.
Cut off the feet close to the joints, leaving some skin to fold over the ends.
Remove the liver and heart, reserving them with the feet for gravy.
Truss the legs.
Fill the body with stuffing.
Sew or tie the pig up with buttered twine.
Roast and baste
Rub the outside of the pig with lard to prevent blistering.
Baste the pig well while roasting.
Just before it's done, rub the pig with a feather dipped in olive oil.
Make the gravy and serve
Drain the gravy from the pan into a saucepan.
Skim off the fat from the gravy.
Mix flour with the finely chopped liver and heart. Add salt and pepper to the mixture.
Simmer for 15 minutes.
Add caramel to the gravy.
Serve the gravy in a tureen with the pig.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Bulk out the stuffing, adding soft starch and moisture as it cooks inside the pig.
- Butter
- Adds richness and moisture to the stuffing and twine coating.
- Onions
- Add sweetness and moisture to the stuffing as they cook down.
- Flour
- Thickens the gravy so it coats the back of a spoon.
- Caramel
- Darkens the gravy and adds a deeper, slightly sweet colour and flavour.
- Lard
- Fat on the skin that promotes even browning and helps prevent blistering.
The step that matters
Rub the pig with a feather dipped in olive oil just before it's done. Oil applied late adds sheen and a golden finish without the long cooking that would let it darken or burn. Applying it too early, or too heavily, can make the skin greasy and uneven.
Swap the onion
