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
Prepare the flavouring
Simmer vinegar and water with onion, horse-radish, cloves, mace, and black pepper until the onion is tender.
Chop the onion small with the anchovies.
Boil for a few minutes with the ketchup.
Thicken with egg yolks
Beat the egg yolks and strain them.
Gradually mix the hot liquid with the egg yolks, stirring constantly over gentle heat.
Keep the sauce moving to prevent curdling 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 sharp acidity that balances the richness of the yolks and anchovies.
- Anchovies
- Contribute savoury depth and umami to the sauce once they break down in the liquid.
The step that matters
Adding the hot liquid to the yolks. Egg yolks scramble if they meet heat too fast. Adding the hot liquid gradually and stirring constantly tempers the yolks, so the sauce thickens smoothly instead of curdling.
Swap the mace
How well each one fits the dish's main ingredients (vinegar, onion, horse, radish, clove, pepper, ketchup):
