Why it works: Pepper and allspice match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 6,395 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Boiled Roast
Ingredients
Directions
Prepare the roast
Place the roast in an aluminum steamer kettle with melted lard or suet to prevent sticking.
Season the roast with salt, pepper, and allspice.
Brown the roast on both sides.
Boil and steam
Pour enough boiling water over the roast to cook it through.
Peel and slice the sweet potatoes, season with salt and pepper, and place them in the steamer.
Steam the sweet potatoes over the roast for about 30 minutes, keeping the kettle tightly covered.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roast
- Forms the main protein; browning and gentle boiling cook it through with moist heat.
- Lard or suet
- Coats the kettle to prevent sticking and adds fat for browning the roast.
- Allspice
- Adds aromatic, warm flavor to the outside of the roast.
- Sweet potatoes
- Steam in the kettle until tender, absorbing flavor and moisture from the roast.
The step that matters
Keep the kettle tightly covered while steaming. A tight lid traps steam so the sweet potatoes cook evenly in moist heat. Lifting the lid lets steam escape, lowering and uneven the temperature and slowing cooking.
Swap the sweet potato
How well each one fits the dish's main ingredients (pepper, allspice):
- Capsicumfits better
- Carrotfits better
- Mustardfits better
- Sweet potatothe original
Fit is the average pairing score against pepper, allspice. Candidates are from the same food group and used in at least 100 recipes.
