Why it works: Thyme and carrot match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 4,563 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
To Braise the Inside of a Sirloin of Beef
Ingredients
Directions
Prepare
Remove the fillet from the joint and trim off all skin, smoothing the surface.
Roll bacon strips in thyme, spices, pepper, and salt.
Lard the fillet with the bacon strips and tie it with kitchen twine.
Braise
Line a braising pan with bacon slices, then add a layer of beef or veal, onions, bay leaves, carrots, and sweet herbs.
Place the fillet on top, cover with bacon, and add meat trimmings around it.
Pour in the beef broth or gravy and simmer gently for 2.5 hours.
Finish the gravy
Remove the fillet and keep it hot; strain the gravy and reduce it by boiling until thick enough to glaze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin beef
- Forms the main joint that is larded, braised and sliced for serving.
- Bacon
- Lards the lean fillet and bastes it with fat as it cooks, adding savoury flavour.
- Onions
- Break down during braising, adding sweetness and body to the surrounding liquid for the gravy.
- Carrots
- Release sugars and aroma into the braising liquid, sweetening and rounding the gravy.
- Beef broth or gravy
- Provides the braising liquid, which gently cooks the meat and forms the base of the gravy.
The step that matters
Simmer gently for 2.5 hours. A gentle simmer keeps the lean fillet tender and moist; vigorous boiling toughens muscle fibres and dries the meat. The liquid should barely bubble.
Swap the onion
How well each one fits the dish's main ingredients (beef, thyme, pepper, carrot):
- Parsnipfits better
- Capsicumfits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against beef, thyme, pepper, carrot. Candidates are from the same food group and used in at least 100 recipes.
