Why it works: Parsley and watercress match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 469 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Fillet of Beef
Ingredients
Directions
Prepare the beef
Remove the fillet from the sirloin and carve it to create six slots.
Fill the slots alternately with minced parsley and grated bacon.
Cook
Place the fillet in a Dutch oven over a bright flame for 20 minutes.
Meanwhile, cook the tomatoes in the oven.
Serve
Arrange the beef in the center of a serving dish with the tomatoes around it.
Garnish with a wreath of well-washed watercress.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef fillet
- Forms the main body of the dish and provides the meaty, tender centre.
- Grated bacon
- Adds fat and savoury flavour that keeps the lean fillet moist as it cooks.
- Tomatoes
- Add moisture and gentle acidity that balances the rich beef and bacon.
The step that matters
Place the fillet in a Dutch oven over a bright flame for 20 minutes. High direct heat browns the outside of the beef through the Maillard reaction, creating deep flavour. The interior only stays tender if the time is controlled, because overcooking tightens the muscle fibres and dries the meat.
Swap the tomato
How well each one fits the dish's main ingredients (beef, parsley, watercress):
