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 ↓
Soft Roes of Herrings in Cases
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
Preheat the oven to 400°F (200°C).
Grease a round or square paper case with butter.
Boil the herrings until cooked, then carefully remove the roes.
Place the roes whole into the prepared case.
Bake and serve
Sprinkle with pepper, coarse sea salt, grated bread, and parsley.
Dot with small bits of butter.
Bake in the hot oven until firm.
Add Maitre d’ Hotel Sauce Maigre and lemon juice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring roe
- Forms the main body of the dish and sets to a firm, tender texture when baked.
- Grated bread
- Absorbs moisture and helps form a light, lightly browned crumb crust on top.
- Butter
- Adds richness and moisture, and helps the crumbs brown in the oven.
- Lemon juice
- Adds acidity that brightens the rich flavour of the roe and butter.
The step that matters
Bake in the hot oven until firm. Roe proteins set when heated, so overbaking can make them dry and rubbery, while underbaking leaves them soft and loose. Watch for a firm, just-set texture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
