Why it works: Mace and clove are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 8,400 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓
Scalloped Mackerel with Tomato
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish and tomato
Freshen the mackerel by soaking it in water to cover, flesh-side down, on a rack for 18 to 24 hours.
Cook the tomatoes, bay leaf, mace, onion, and cloves for 20 minutes. Add baking soda to the cooked mixture. Strain the mixture.
Remove bones and skin from the mackerel. Break the fish into bits.
Make the sauce
Melt the butter in a saucepan. Cook the cornstarch in the melted butter.
Gradually add the strained tomato pulp until it thickens.
Bake and serve
Butter a baking dish.
Layer bread crumbs, mackerel, and repeat until all fish is used. Pour the tomato mixture over the layers. Top with bread crumbs and bits of butter.
Bake at 350°F (175°C) until golden.

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, providing the fish layers and its flavour.
- Tomatoes
- Provide acidity and moisture, forming the base of the sauce.
- Cornstarch
- Thickens the strained tomato liquid into a smooth sauce as it cooks.
- Butter
- Adds richness and fat, and helps the cornstarch cook into the sauce.
- Bread crumbs
- Add structure between the layers and browning on the top crust.
The step that matters
Thickening the sauce with cornstarch. Cornstarch must be cooked in the melted butter and the tomato added gradually, so the starch granules swell evenly. Adding liquid too fast can leave lumps and a thin, uneven sauce.
Swap the mace
How well each one fits the dish's main ingredients (tomato, onion, clove, butter, bread):
- Thymefits better
- Garlicfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against tomato, onion, clove, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
