Why it works: Parsley and thyme 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 ↓
Rolled Flank Steak
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the steak
Score the surface of the flank steak on both sides with a sharp knife.
Rub one side with coarse sea salt and black pepper, then sprinkle with onion juice, chopped parsley, and thyme or savory.
Roll up the steak tightly and tie it with kitchen twine.
Brown and make the gravy
Melt dripping in a frying pan and brown the meat on all sides until seared.
Transfer the browned meat to a deep pan or casserole.
In the frying pan, add 1 tablespoon flour to the fat and stir until well-browned.
Gradually add 1½ cups water or stock, stirring until thick and smooth.
Season the sauce with salt and pepper, then add 1¼ cups vinegar or claret and pour around the meat.
Bake and serve
Cover closely and bake in a 350°F (175°C) oven for 2 hours.
Remove the twine, place the meat on a hot platter, and pour the gravy around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flank steak
- Tough, lean meat that becomes tender during long, moist cooking.
- Flour
- Browned in the fat, it thickens the gravy and adds a toasted flavor.
- Dripping
- Fat that sears the surface of the meat and carries flavor into the gravy.
- Vinegar or claret
- Adds acidity that brightens the gravy and helps tenderize the meat.
- Onion juice
- Adds savory onion flavor that penetrates the meat during rolling.
The step that matters
Browning the meat on all sides. A deep, even sear builds browned flavor through the Maillard reaction. Pale surfaces produce a flat-tasting gravy and a less appealing crust, so the meat must be dry and the pan hot enough.
Swap the onion
How well each one fits the dish's main ingredients (pepper, parsley, thyme, flour, vinegar):
- Shallotfits better
- Parsnipfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against pepper, parsley, thyme, flour, vinegar. Candidates are from the same food group and used in at least 100 recipes.
