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 fillets
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.
Place each grilled fillet on a slice of fried bread (crout) and season well.
Cook the tomatoes
Slice the tomatoes thickly, place in a buttered dish, and cook in a 350 °F (175 °C) oven for 5 minutes.
Top each fillet with a slice of cooked tomato and garnish with spinach puree.
Make the sauce
For the sauce, chop the shallot and mushrooms, then fry them in butter.
Add stock, glaze, sherry, and herbs, then simmer for 20 minutes.
Strain the sauce, thicken with cornflour, season with salt and pepper, and bring to a boil.

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, cooked quickly to stay tender inside.
- Butter
- Adds richness and carries flavour when frying the shallot and mushrooms.
- Cornflour
- Thickens the strained sauce to a smooth, glossy consistency.
- Stock
- Forms the liquid base of the sauce and adds savoury depth.
- Sherry
- Adds acidity and aroma to the sauce as it simmers.
- Tomatoes
- Add moisture and gentle acidity that balance the rich beef.
The step that matters
Thickening the sauce with cornflour. Cornflour must be fully cooked after it is stirred in, or the sauce stays cloudy and tastes raw. Bringing it to a boil activates its thickening starch evenly and keeps lumps from forming.
