Why it works: Spinach and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 198 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Fillets of Beef a LA Francaise
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 beef and tomatoes
Cut the beef fillet into neat rounds, each ½ inch thick and 3 inches in diameter.
Grill the fillet rounds for 1 minute on each side.
Slice the tomatoes thickly and cook in a buttered dish in a 350°F (175°C) oven for 5 minutes.
Make the sauce
For the sauce, chop the shallot and mushrooms and fry them in butter.
Add stock, glaze, sherry, and herbs, then simmer for 20 minutes.
Strain the sauce, thicken with cornflour, season, and bring to a boil.
Assemble and serve
Serve one fillet on each slice of fried bread and season well.
Place a slice of cooked tomato on each fillet and garnish with spinach puree.

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 protein, cooked quickly so it stays tender and browned on the outside.
- Butter
- Adds richness and helps fry the shallot and mushrooms for flavour.
- Cornflour
- Thickens the strained sauce to a glossy, coating consistency.
- Tomatoes
- Add moisture and gentle acidity that balances the rich beef and sauce.
- Sherry
- Adds aromatic depth and acidity to the sauce as it simmers.
- Stock
- Provides the liquid base that carries the savoury flavour of the sauce.
The step that matters
Thickening the sauce with cornflour. Cornflour must be stirred into the liquid and brought to a boil to fully gelatinise its starch. Otherwise the sauce stays thin or tastes floury.
