Why it works: Sugar and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
To Cure Shad
Ingredients
Directions
Salt the shad
Clean and wash the shad.
Place a layer of coarse sea salt in a vessel.
Add a layer of shad, then more salt, repeating until all shad are layered.
Cover the top with salt and let sit for 24 hours.
Remove the shad and wipe them dry.
Cure and finish
Mix brown sugar, saltpetre, rock salt, and fine salt in equal proportions.
Layer this mixture in the vessel, alternating with layers of shad until covered.
Put a thick layer of the mixture on top.
Remove shad from brine, wash, and boil or soak for a few hours.
Wipe dry, then broil over a clear fire until light brown on both sides, basting with butter.

What each ingredient does
- Shad
- The main fish, which is salted and cured so it keeps and firms.
- Coarse sea salt
- Draws moisture out of the fish and begins the curing process.
- Brown sugar
- Adds sweetness and helps the surface brown during broiling.
- Saltpetre
- Helps preserve the color of the cured fish.
- Butter
- Adds fat and moisture to the surface while broiling, promoting browning.
The step that matters
Wipe the shad dry before broiling. Surface moisture left from washing or soaking turns to steam instead of letting the skin brown, so the fish cooks unevenly and browns poorly. Drying first lets the surface caramelise over a clear fire.
