Why it works: Shallot and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 859 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Herrings Stuffed with Mustard Butter
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mustard butter
Mix 4 tablespoons of butter, 1 teaspoon of dry mustard, and 1 teaspoon of lemon juice on a plate.
Form the mixture into a pat and refrigerate until firm.
Prepare the herrings
Wash the herrings and dry them.
Remove the heads of the herrings.
Split the herrings open and take out the backbone.
Make the stuffing
Boil the roes in water for 10 to 15 minutes, then chop them coarsely.
Mix the chopped roes with 1¾ cups of white bread crumbs, 1 tablespoon of oiled butter, anchovy essence or paste, and ¼ teaspoon finely chopped shallot or onion.
Season the mixture with salt and pepper to taste.
Stuff, bake and serve
Stuff the mixture into the herrings and close them.
Brush the herrings with warm butter.
Bake in a 350°F (175°C) oven for about 20 minutes.
Top each herring with a pat of mustard butter before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Form the main body of the dish, cooking through while holding the stuffing.
- Bread crumbs
- Absorb moisture and bind with the roe to give the stuffing a soft, cohesive texture.
- Butter
- Adds richness and moisture, and helps the fish brown lightly in the oven.
- Dry mustard
- Adds sharp, pungent flavour to the butter topping that cuts the richness of the fish.
- Anchovy essence or paste
- Adds savoury depth and salty umami to the stuffing.
The step that matters
Close the herrings securely before baking. If the stuffing is packed too loosely or the fish is not closed well, the filling can spill out during baking, leaving the fish dry and uneven.
