Why it works: Parsley and butter are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
To Boil Perch
Ingredients
Directions
Prepare
Wipe or wash the perch to remove slime.
Scrape off the scales and clean the insides thoroughly.
Remove the gills and cut off the fins.
Boil
Place the perch in equal parts of cold and boiling water, salted as for mackerel.
Boil for 8 to 10 minutes unless the perch is very large.
Serve
Dish the perch on a napkin and garnish with curled parsley.
Serve with melted butter or Sauce Maigre.

What each ingredient does
- Perch
- Provides the main flesh, which firms and turns opaque as it cooks in gently boiling water.
- Melted butter
- Adds richness and fat to balance the mild, lean flesh of the fish.
The step that matters
Boil for 8 to 10 minutes unless the perch is very large. Fish proteins set quickly in hot water and turn dry and tough if overcooked. Timing must match the fish's size, so very large perch need longer and should be checked for flakiness rather than relying only on the time given.
