Why it works: Shallot and flour match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,081 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Curried Sardines
Ingredients
Directions
The book says “a sharp oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Make the sauce
Open the tin of sardines and pour the oil into a frying pan.
Fry the chopped shallot in the oil until pale yellow.
Pour off the oil.
Add the curry powder and flour, frying briefly.
Moisten the mixture with stock or water and boil for a few minutes.
Assemble and bake
Skin the sardines.
Place them in a buttered gratin dish.
Pour the sauce over the sardines.
Sprinkle with breadcrumbs and bits of butter.
Bake in a hot oven (400°F/200°C) for 10 minutes.
Serve
Serve with boiled rice.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Provide the main protein and their oil, which carries the curry flavour into the frying pan.
- Shallot
- Softens into the oil and adds a mild, sweet onion-like base to the sauce.
- Curry powder
- Supplies the spiced aroma and colour that define the sauce; frying it briefly in oil wakes up its flavour.
- Flour
- Thickens the sauce as it cooks with the curry powder and stock.
- Breadcrumbs
- Form a crisp, browned topping during baking.
The step that matters
Frying the curry powder and flour. Cooking spices briefly in fat releases their aroma, but burning them makes the sauce bitter. Keep the heat moderate and stir constantly, then add the liquid promptly so the flour can thicken smoothly.
Swap the shallot
How well each one fits the dish's main ingredients (flour, butter, rice):

- Arrowrootfits about as well
- Okrafits about as well
Fit is the average pairing score against flour, butter, rice. Candidates are from the same food group and used in at least 100 recipes.
