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 ↓
Fresh Mackerel, Fried
Ingredients
Directions
Prepare the fish
Trim and split the mackerels through the back, removing heads, tails, and spines.
Rinse with cold water and wipe dry.
Mix salt and pepper, then rub on both sides of the fish.
Coat the fish
Beat the egg in a bowl until light.
Dust the mackerel with flour, dip in the egg, then coat with cracker crumbs.
Let the coated fish sit for 20 minutes to dry.
Fry and serve
Cut the larding pork into small pieces and fry in a pan until light brown.
Add the fish to the pan, frying until light brown on both sides.
Transfer the mackerels to a hot dish, garnish with parsley and lemon, cut into pieces, and serve with baked potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main body of the dish, cooking to a flaky, tender texture inside the crisp coating.
- Flour
- Dry layer that helps the egg adhere and gives the coating a base for browning.
- Egg
- Binding layer that holds the cracker crumbs to the fish during frying.
- Soda crackers
- Crumb coating that fries to a golden, crisp crust.
- Larding pork
- Renders fat into the pan, providing the medium for frying and adding savory flavor.
The step that matters
Let the coated fish sit for 20 minutes to dry. Resting the coating lets the flour, egg, and crumbs set and bond, so the crust is less likely to slip off or steam loose in the hot fat.
Swap the potato
How well each one fits the dish's main ingredients (pepper, egg, flour, pork, parsley, lemon):
- Shallotfits better
- Spinachfits better
- Asparagusfits about as well
- Potatothe original
Fit is the average pairing score against pepper, egg, flour, pork, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
