Why it works: Thyme and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Roast Rump of Beef
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Lard the rump of beef across the grain.
Place the larded beef in a dish with wine, oil, pepper, salt, onions, thyme, and parsley.
Marinate for two days, turning once or twice.
Roast
On the third day, roast the beef at 400°F (200°C).
When half roasted, add a tablespoon of the marinade to the gravy in the pan.
Baste frequently during roasting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump of beef
- Forms the main meat that is cooked and sliced for serving.
- Onions
- Add savory sweetness and aroma to the marinade and pan gravy.
- Chablis (white wine)
- Adds acidity to the marinade, helping to tenderise the meat.
- Oil
- Carries flavour in the marinade and helps the surface brown and stay moist.
The step that matters
Basting during roasting. Regular basting keeps the surface moist and carries juices back over the meat, supporting even browning and preventing the outside from drying out before the centre is cooked.
Swap the onion
How well each one fits the dish's main ingredients (beef, white wine, thyme, parsley, pepper):
