Why it works: Lemon and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,973 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Beef Fillets a LA Naunton
Ingredients
Directions
Marinate
Flatten the fillets and place them on a dish.
Mix lemon juice, salad oil, pepper, cayenne, thyme, bay leaf, and chopped onion.
Marinate the fillets in the mixture for 2 hours, turning often.
Cook the beef and gravy
Drain the fillets and fry them in hot butter for 7-10 minutes until gravy clots on the surface.
Place the fillets on a hot dish.
Prepare the gravy by boiling brown sauce, roast beef gravy, sherry, and lemon juice; season to taste.
Assemble and serve
Arrange the fillets overlapping in the center of a hollowed block of crust.
Pour half the gravy over the fillets and place cooked macaroni around them.
Pour the remaining gravy over the macaroni and garnish with glazed croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef fillets
- The main protein; frying sears the surface and sets the texture of the meat.
- Salad oil
- Carries the lemon, onion and herbs into the meat during marinating and keeps it moist.
- Lemon juice
- Acidity in the marinade tenderises the beef and brightens the gravy.
- Chopped onion
- Adds aroma and savoury flavour to the marinade.
- Brown sauce
- Forms the body and rich, savoury flavour of the gravy.
- Roast beef gravy
- Adds concentrated meaty flavour and richness to the sauce.
The step that matters
Frying the marinated fillets. Fry in hot butter only until the surface browns and the pan juices begin to clot; overcooking toughens the protein and dries the meat. Drain well first so excess marinade does not steam the fillets instead of browning them.
Swap the onion
How well each one fits the dish's main ingredients (beef, lemon, pepper, thyme, butter, sauce, sherry):

Fit is the average pairing score against beef, lemon, pepper, thyme, butter, sauce, sherry. Candidates are from the same food group and used in at least 100 recipes.
