Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Turnip and Rice Soup
Ingredients
Directions
Make the soup
In a saucepan, combine the rice, onion, and white peppercorns.
Add the water and bring to a boil, then cook for 1 hour.
Rinse the mixture through a sieve back into the saucepan.
Stir in the milk, salt, and black pepper, and heat until boiling.
If desired, add the butter to the boiling mixture.
Serve
Serve in a warm tureen and garnish with chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Thickens the soup as its starch breaks down during long simmering.
- Milk
- Adds creaminess and a mild sweetness to the soup.
- Onion
- Builds savory depth as it softens and flavors the cooking liquid.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
The step that matters
Rinse the mixture through a sieve. Pressing the cooked rice and onion through the sieve releases starch and softens solids, giving the soup a smooth body. Rinsing too little leaves grainy texture.
