Why it works: Anchovy and sauce are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 2,057 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Roe Sauce
Ingredients
Directions
Prepare the roe
Cook the roe in a little water until tender.
When cool, remove any skin and mash the roe with the back of a wooden spoon.
Make the sauce
Add the mustard, anchovy sauce, and vinegar, then stir into the melted butter.
Season with salt and pepper to taste.
Simmer gently for 15 minutes, then strain and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod's roe
- Provides the main body and flavour of the sauce once cooked and mashed.
- Melted butter
- Forms the rich, smooth base that carries the other flavours.
- Made mustard
- Adds sharpness that balances the richness of the butter and roe.
- Anchovy sauce
- Contributes savoury depth and a salty, umami note.
- Vinegar
- Adds acidity that brightens the sauce and cuts through the fat.
The step that matters
Simmer gently for 15 minutes. Heating the sauce too hard can cause the butter to separate and the roe to toughen or curdle, so a gentle simmer keeps the sauce smooth.
Swap the mustard
