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 ↓
Mackerel, with Fine Herbs
Ingredients
Directions
The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Grease a baking tin with butter.
Fry the minced herbs, mushrooms, shallots, and parsley in a pan until softened. Season with pepper and salt.
Spread the herb mixture on the bottom of the baking tin.
Assemble and bake
Place the mackerel on top of the herbs and cover with bread crumbs.
Moisten the crumbs with gravy or white wine and dot with pieces of butter.
Bake for 15 to 20 minutes until browned.
Serve with a squeeze of lemon juice on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main protein, cooking gently on the herb bed until it turns flaky.
- Butter
- Adds richness and helps the crumbs brown in the oven.
- Mushrooms
- Add moisture and earthy flavor to the herb base as they soften.
- Shallots
- Add mild sweetness and aroma when softened in the pan.
- Bread crumbs
- Form a crust that browns and helps hold moisture in the fish.
The step that matters
Baking time and browning. Mackerel is delicate and cooks quickly at low heat. Checking at the short end of the 15 to 20 minute range helps keep the fish moist while the crumbs brown.
