Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Herrings, Roes Of, on Toast
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the roe
Wash the soft roes of the herrings in cold salt water and place them in a deep fire-proof dish.
In a small saucepan, combine boiling water, French vinegar, salt, peppercorns, and bay leaves. Bring to a boil, skim, and strain over the roes.
Cover the dish with buttered paper and bake in a 350°F (175°C) oven for 10 minutes.
Toast and finish
While the roes are baking, toast the bread and butter both sides while hot.
Drain the roes and place one on each piece of toast. Add small pieces of butter on top and return to the oven for 5 minutes.
Remove from the oven, squeeze a few drops of lemon juice over each, sprinkle with chopped parsley and cayenne, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soft roes of herrings
- Provide the rich, soft, delicate main body of the dish that cooks gently into a custardy texture.
- Butter
- Adds richness and moisture to the toast and helps it brown lightly.
- Bread
- Forms a crisp base that holds the roe and absorbs the buttery juices.
- French vinegar
- Adds sharp acidity to the poaching liquor, balancing the richness of the roe.
The step that matters
Poaching the roes in the hot vinegar liquor. The roes are delicate and can break up or turn rubbery if the liquor boils too hard. Gentle heat in the covered dish sets them softly while the vinegar flavours them.
