Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cod's Roe
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Cut the cod's roe into slices and serve with toast, butter, lemon, and cayenne pepper.
Boil the sheep's brains and flavor with cream.
Cut the halfpenny rolls in half and remove the crumb while hot.
Place the rolls in the oven at 400°F (200°C) to crisp.
Sprinkle the rolls with cayenne pepper and coarse sea salt.
Cover the rolls with fried bread-crumbs and serve hot.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
