Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Barbecued Pork Sandwiches
Ingredients
Directions
Cook the pork
Cut roast into 2‑inch cubes; place in slow cooker with onion, barbecue sauce, hot pepper sauce, and marmalade. Cover and cook on Low for 6‑8 hours, until tender.
Remove pork and onions from slow cooker with slotted spoon. Shred pork and set aside.
Thicken and serve
Combine cornstarch and water and add this mixture to juices in slow cooker, stirring to blend well.
Cover and cook on High for 1 minute; return the pork to slow cooker and heat through on High for 10 minutes.
Serve on sandwich buns.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork shoulder
- Slow cooking breaks down connective tissue, so the meat becomes tender and easy to shred.
- Barbecue sauce
- Provides the main flavor and, with the juices, forms the sauce that coats the shredded meat.
- Orange marmalade
- Adds sweetness and a hint of acidity that balances the spicy, savory sauce.
- Cornstarch
- Thickens the cooking juices into a glossy sauce that clings to the pork.
- Onions
- Soften during cooking and add sweetness and savory depth to the sauce.
The step that matters
Thickening the juices with cornstarch slurry. Cornstarch must be mixed with cold water first and then heated in the liquid; it thickens only when the mixture reaches a simmer. Added dry or unmixed, it clumps and the sauce stays thin.
Swap the orange
How well each one fits the dish's main ingredients (pork, onion, sauce, pepper):
- Avocadofits better
- Limefits better
- Mangofits better
- Orangethe original
Fit is the average pairing score against pork, onion, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes.
