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 ↓
Baked Mackerel
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Wash the mackerel in cold water, cut off the tails and heads, and open the fish down the back.
Wipe them inside and out with a soft cloth and lay them open, skin down, in a well-greased baking dish.
Sprinkle salt and pepper on them, squeeze a little lemon juice over, and cover with greased kitchen paper.
Bake and serve
Bake in a moderate oven (350°F / 175°C) for about 20 minutes or until done.
For maitre d'hotel butter, chop parsley finely, wash it, and wring it dry.
Mix parsley with butter, a little pepper, salt, and lemon juice until smooth.
Spread the maitre d'hotel butter on each fish and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Firm, oily flesh that stays moist and richly flavoured when baked.
- Butter
- Adds fat and richness, carrying flavour and keeping the fish moist.
- Lemon juice
- Adds acidity that brightens the fish and balances its richness.
- Parsley
- Adds fresh, herbal aroma to the maitre d'hotel butter.
The step that matters
Covering the fish with greased kitchen paper. The cover traps moisture so the fish steams gently in the oven and does not dry out. Greasing it stops it sticking to the flesh and skin when lifted.
“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.
