Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fried Perch
Ingredients
Directions
Lay the cleaned and dried perch side by side on a board or large dish.
Sprinkle with coarse sea salt and dredge with flour on both sides.
Heat lard or beef dripping in a frying pan over medium heat until boiling.
Test the heat by dipping the tail of a fish; if it crisps immediately, it's ready.
Ensure there is enough lard to cover the fish entirely.
Fry the fish for 5 minutes on one side, then turn and fry for another 5 minutes.
Skim the lard before adding the fish.
Serve with melted butter flavored with anchovy.
