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 ↓
Herring Roes on Toast
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the roe
Preheat the oven to 400°F (200°C).
Place the herring roe in a well-buttered sauté pan.
Sprinkle the chopped shallot over the roe.
Add the lemon juice and cover with a piece of buttered paper.
Bake for about 8 minutes.
Prepare the toast
Mix the anchovy paste with half an ounce of butter and spread it over the toasted bread.
Cut the bread into strips the size of the roe.
Assemble and serve
Remove the roe from the pan and fasten each on a tiny silver skewer.
Arrange the roe on the toast, garnish with fresh parsley, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring roe
- Forms the main body of the dish, cooking to a soft, delicate texture.
- Anchovy paste
- Adds a salty, savoury flavour to the buttered toast.
- Butter
- Carries flavour and keeps the roe and toast moist as they cook.
- Shallot
- Contributes a mild, sweet onion-like aroma during baking.
- Lemon juice
- Adds acidity that brightens the rich roe and butter.
The step that matters
Baking the roe. Roe is delicate and can dry out or toughen if overcooked, so it should be baked just until set. Covering it with buttered paper traps steam and moisture, helping it stay tender in the hot oven.
