Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pork Chops with Onions
Ingredients
Directions
Prepare the pork
Season the pork chops on both sides with salt and pepper.
Brush the chops with olive oil and roll them in bread crumbs.
Make the onions
Slice the onions and place them in a saucepan with butter.
Cook the onions, stirring frequently, then add boiling water, salt, and pepper.
Simmer the onions for 45 minutes, then strain and mix in a little mustard.
Cook and serve
Grill the chops over a clear fire, turning them only once.
Serve the chops on top of the onions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork chops
- Provide the main meat, which the breadcrumb coating helps brown and protect during grilling.
- Bread crumbs
- Form a crisp, browned coating on the outside of the chops.
- Onions
- Soften and sweeten as they cook slowly, forming the base the chops sit on.
- Butter
- Adds fat and richness, helping the onions cook gently and taste mellow.
- Mustard
- Adds a sharp, tangy note that balances the sweetness of the onions.
The step that matters
Turning the chops only once. Flipping meat repeatedly slows surface browning and can dry the chops; turning once lets a crust form on the first side and keeps juices inside.
