Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Roast Fillet
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove sinewy skin and gristle from the top of the fillet and most fat from the underside.
In a baking pan, layer thin slices of larding pork, onion, carrot, turnip, and celery.
Place the fillet on top of the vegetables.
Pour 1 cup of brown stock over the fillet, then season with salt, pepper, parsley, bay leaf, and cloves.
Roast
Cook in a hot oven (400°F / 200°C) for 30 minutes, basting frequently.
Once done, drain off the gravy and remove excess grease.
Make the sauce and serve
In a pan, melt 1 tablespoon of butter and mix with 1 tablespoon of flour until browned.
Stir in the gravy and an additional cup of brown stock, cooking until it boils.
Add the chopped mushrooms and let simmer for 5 minutes.
Finish with a splash of Madeira or sherry, then pour around the fillet and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fillet of beef
- Is the main cut that is roasted, and its fat and gristle are trimmed first.
- Larding pork
- Bastes the fillet with fat as it cooks, keeping the lean meat moist and adding flavour.
- Butter and flour
- Form a browned roux that thickens the gravy into a smooth, rich sauce.
- Mushrooms
- Add earthy flavour and body to the sauce as it simmers.
- Madeira or sherry
- Adds a sweet, fortified aroma and depth to the finished sauce.
The step that matters
Browning the butter and flour roux. Cooking the flour in fat until it turns golden removes raw starch taste and gives the sauce colour and nutty depth. Stopping too early leaves a pasty flavour, while over-browning makes it bitter and dark.
Swap the onion
How well each one fits the dish's main ingredients (beef, pork, carrot, turnip, celery, pepper, parsley):

Fit is the average pairing score against beef, pork, carrot, turnip, celery, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
