Why it works: Mustard and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Boiled Salad Dressing
Ingredients
Directions
Combine vinegar and butter in a porcelain or granite pan.
Heat the mixture until the butter melts.
Remove the pan from heat and let the mixture cool.
Beat the eggs until light, then add mustard, salt, celery salt, pepper, and milk.
Pour the egg mixture into the cooled vinegar and butter mixture and cook for a few minutes.
When it begins to thicken, remove from heat and stir until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they cook and set into a creamy, smooth texture.
- Butter
- Adds richness and fat that gives the dressing a smooth, rounded mouthfeel.
- Vinegar
- Provides the sharp acidity that defines the dressing's tang.
- Milk
- Dilutes the mixture and adds moisture and mild richness.
- Mixed mustard
- Adds sharp flavor and helps emulsify the fat into the dressing.
The step that matters
Pour the egg mixture into the cooled vinegar and butter mixture. The mixture must be cooled before the eggs are added, because eggs scramble when exposed to high heat. Gentle cooking and constant stirring let the egg proteins thicken the dressing evenly.
Swap the celery

- Tarragonfits better
