Why it works: Horse and radish work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 529 recipes. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓
Fish Sauce Without Butter
Ingredients
Directions
Make the base
Simmer vinegar and water with onion, horseradish, and spices until the onion is tender.
Chop the onion small with the anchovies and boil for a few minutes with the ketchup.
Finish the sauce
Beat the egg yolks and strain them.
Gradually mix the hot liquor with the yolks, stirring constantly over gentle heat.
Keep the sauce hot until it thickens like melted butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce as they set gently with heat, giving it a smooth, rich body.
- Vinegar
- Adds sharpness that balances the richness of the egg yolks.
- Anchovies
- Contribute savory depth to the sauce once cooked down with the onion.
- Walnut ketchup
- Adds concentrated savory and tangy flavour to the sauce.
The step that matters
Adding the hot liquor to the yolks. If the hot liquid is poured in too quickly or the heat is too high, the egg yolks can scramble instead of thickening smoothly. Adding it gradually while stirring keeps the yolks evenly warmed so the sauce becomes silky.
Swap the mace
How well each one fits the dish's main ingredients (vinegar, onion, horse, radish, clove, pepper, walnut):
