Why it works: Parsley and lemon 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 ↓
Scalloped Roe
Ingredients
Directions
Prepare
Boil the roe as for fried roe, then drain and break it up lightly with a fork.
Assemble
In a baking dish, sprinkle a layer of roe, then add half the beaten egg yolk over the top.
Sprinkle lightly with chopped parsley, season with salt, pepper, and lemon juice.
Add a layer of white sauce, then repeat the layers of roe, egg, seasoning, and sauce.
Cover with bread crumbs and bits of butter, then bake until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roe
- Forms the bulk of the dish and provides its main texture and flavour.
- Egg yolk
- Enriches the layers and helps bind them as it cooks.
- White sauce
- Adds moisture so the layers stay creamy rather than dry.
- Bread crumbs
- Form a crisp, browned topping over the baked dish.
- Butter
- Adds fat that aids browning of the crumb topping and adds richness.
The step that matters
Baking until brown. The top should be browned, not just heated through. Bread crumbs and butter brown through Maillard reactions and caramelisation at oven heat, so watch the colour rather than only the clock, and avoid overbaking, which can dry the layers under the crust.
