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 ↓
Fillet of Beef
Ingredients
Directions
Prepare
Carefully cut out the fillet from the sirloin, leaving a small portion of fat on the sides.
Lard the fillet lengthwise with small pieces of fat bacon.
Rub the fillet with pounded mace, pepper, and coarse sea salt.
Cook
Place the fillet in a stewpan and cover the top with coarse paste.
Cook over hot ashes for three to four hours.
Make the sauce
Prepare beef stock using white wine instead of water, simmering slowly with the pot covered to retain steam.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin of beef
- Provides the lean fillet meat that forms the main body of the dish.
- Fat bacon
- Larding adds fat that melts during the long cook, keeping the lean fillet moist and tender.
- White wine
- Replaces water in the stock, adding acidity and aroma to the liquid.
- Coarse sea salt
- Seasons the surface of the meat and helps draw out flavor.
The step that matters
Cooking over hot ashes for three to four hours. Long, gentle heat is needed to cook the fillet through without drying it. Too much heat dries the surface before the centre is done, so the fillet needs steady, moderate heat.
Swap the mace
How well each one fits the dish's main ingredients (beef, pepper, white wine, onion, mustard):
- Garlicfits better
- Thymefits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against beef, pepper, white wine, onion, mustard. Candidates are from the same food group and used in at least 100 recipes.
