Why it works: Olive and mustard match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 5,950 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Deviled Eggs
Ingredients
Directions
Prepare the eggs

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks form the creamy filling, while whites provide the edible shell for it.
- Olive oil
- Adds fat that makes the mashed yolk filling smooth and rich.
- Mustard
- Adds sharp acidity and aroma that balances the rich yolks.
- Cold boiled ham
- Adds salty, savory flavor and a firmer meaty texture to the filling.
The step that matters
Cooling the boiled eggs. Plunging boiled eggs into cold water for 30 minutes helps stop overcooking, which keeps yolks creamy and not chalky or grey-ringed, and makes the shells easier to remove cleanly.
