Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Roman Pie of Fish
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Preheat the oven to 350°F (175°C).
Trim and cook the fish fillets in a well‑buttered baking tin for 8‑10 minutes with lemon juice, white pepper, and minced parsley, covered with buttered paper.
Assemble the pie
Line a raised pie mold with puff pastry and sprinkle the inside with cooked vermicelli.
Pack the mold with layers of fish fillets, bearded oysters, and cooked macaroni, sprinkling each layer with minced shallot, vermicelli, white pepper, salt, and grated Parmesan cheese.
Moisten the top with oyster liquor and add ⅓ cup of cream.
Cover with puff pastry and bake until golden.
Serve
Turn out of the mold and serve with brown sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Puff pastry
- Forms the crisp, golden outer shell that encloses the filling.
- Butter
- Adds richness and helps keep the fish moist while it cooks.
- Cream
- Adds moisture and richness to the filling.
- Grated parmesan cheese
- Adds savoury, salty flavour and browning to the layers.
- Bearded oysters
- Contribute a briny, savoury flavour to the filling.
The step that matters
Cooking the fish before layering. Fish fillets cook quickly and can dry out or overcook inside the pie while it bakes. Partly cooking them first, covered to hold in moisture, helps keep them tender.
Swap the white pepper
How well each one fits the dish's main ingredients (fish, lemon, parsley, butter, oyster, shallot, parmesan cheese):
- Capersfits better
- Tarragonfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against fish, lemon, parsley, butter, oyster, shallot, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
