Why it works: Lemon and saffron match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 538 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Sole Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Fillet the soles and place them in a stewpan.
Add salt, pepper, nutmeg, capers, butter, and water.
In a basin, mix flour with lemon juice and saffron.
Stir the mixture into the saucepan to thicken the gravy.
Once cooked, transfer the fish to a pie dish.
Cut the hard‑boiled eggs into quarters.
Bake and serve
Cover with butter puff pastry, decorate with pastry leaves, and brush with egg yolk.
Bake in a hot oven at 400°F (200°C) until golden.
Garnish with parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Provide the main fish, which cooks through in the gravy and forms the pie's filling.
- Butter
- Adds richness and fat, carrying flavour through the gravy and enriching the pastry.
- Flour
- Thickens the gravy so it clings to the fish rather than running out of the pie.
- Eggs
- Hard-boiled eggs add body and texture to the filling; the yolk glaze helps the pastry brown.
- Butter puff pastry
- Forms the flaky, golden crust that encloses the filling and bakes crisp.
- Lemon juice
- Adds acidity that brightens the fish and balances the richness of the butter.
The step that matters
Thickening the gravy. Flour must be mixed smoothly with the lemon juice and saffron before going into the hot liquid, otherwise it forms lumps and the gravy will not thicken evenly.
Swap the saffron
How well each one fits the dish's main ingredients (pepper, nutmeg, capers, butter, flour, lemon, egg):
- Parsleyfits better
- Tarragonfits better
- Marjoramfits better
- Saffronthe original
Fit is the average pairing score against pepper, nutmeg, capers, butter, flour, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
