Why it works: Pepper and thyme match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 11,585 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
The recipe
Ingredients
Contains: milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: walnut
Directions
Prepare the beef
Remove all fat from the beef and pound until tender. Cut into pieces about 2x3 inches.
Heat 1 tablespoon of butter or drippings in a frying pan until very hot. Add the beef pieces and turn them until browned.
Transfer the browned beef to a stew pan. In the same frying pan, add the onions and fry until slightly browned, being careful not to burn them.
Add the browned onions to the beef along with thyme, bay leaf, salt, and pepper.
Simmer the stew
Barely cover the meat with boiling water and add ½ cup of vinegar. Simmer gently for 1½ hours.
Check if the meat is tender; if not, let it simmer gently a little longer. Total cooking time should be about 2 hours.
Thicken and serve
In the frying pan, mix 1 tablespoon of flour with a piece of butter the size of a walnut until browned. Blend with some sauce from the meat and stir until smooth.
Add the flour mixture to the stew pan along with a good pinch of sugar. Mix well and boil for an additional 15 minutes.
Serve with a border of plain boiled macaroni or rice.

Flour and butter share little aroma chemistry, yet 122,858 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Browning and long gentle simmering make the lean meat tender and rich in flavour.
- Onions
- Slow frying sweetens and deepens the savoury base of the sauce.
- Vinegar
- Adds acidity that brightens the rich, slow-cooked sauce.
- Flour
- Browned with butter and blended in, it thickens the sauce and adds a toasty flavour.
- Sugar
- Balances the sharpness of the vinegar and rounds out the sauce.
The step that matters
Browning the flour and butter. Cooking the flour with butter until browned builds nutty flavour and colour, and stirring it smooth with sauce prevents lumps when it thickens the stew.

Fit is the average pairing score against beef, pepper, sugar, onion, vinegar, flour, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
