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 Cutlets, Hash of
Ingredients
Directions
Prepare the pork
Divide the loin into neat cutlets and trim away most of the fat.
Melt the butter or fat in a frying pan.
Add the cutlets and fry until both sides are lightly browned.
Remove the cutlets and keep hot.
Make the sauce
Add the onion to the fat in the pan and fry until browned.
Sprinkle in the flour, season with salt and pepper, and cook for a few more minutes to lightly brown the flour.
Add the stock, vinegar, and mustard, and bring to a boil.
Serve
Pour the mixture over the cutlets arranged in a close circle on a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Remains of cold loin of pork
- Forms the main body of the hash, providing meaty flavour and substance.
- Butter or good fat
- Carries heat for browning the cutlets and onion, adding richness and flavour.
- Spanish onion
- Softens and browns in the fat, adding sweetness and savoury depth to the sauce.
- Flour
- Browns lightly in the pan fat and thickens the gravy as it cooks.
- Good gravy
- Provides the liquid base of the sauce and carries the savoury flavour over the pork.
The step that matters
Lightly browning the flour. Cooking the flour in the fat for a few minutes removes its raw taste and helps it thicken the liquid smoothly. Adding the liquid too early or leaving the flour raw can leave lumps and a pasty flavour.
Swap the onion
How well each one fits the dish's main ingredients (pork, butter, flour, vinegar, mustard, pepper):
- Shallotfits better

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against pork, butter, flour, vinegar, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
