Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Cod’s Roe, Fried
Ingredients
Directions
Heat the butter in a sauté or frying pan.
Cut the cod's roe into 8 slices and fry them lightly on both sides.
Sprinkle the croutes with shallot, parsley, and pepper.
Lay a slice of roe on each crout, add a few grains of cayenne, and serve hot.
For a decorative touch, garnish with strips of gherkin and hard-boiled egg or anchovy butter.
For fresh roe, wash it, cover with boiling water, season with vinegar and salt, boil gently for 10 minutes, cool, slice, and cook as directed.
