Why it works: Carrot and onion are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Puree of Carrots
Ingredients
Directions
In a stewpan, combine sliced carrots, butter, and quartered onions.
Cook until the vegetables are soft.
Add stock and sugar, then stew gently for 3 hours.
Pass the mixture through a fine sieve.
If too thin, reduce on the fire until thickened.
Stir in velouté, skim clear, and adjust thickness to coat the entrée.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide the main body and sweet flavour of the puree.
- Butter
- Adds richness and carries flavour as the vegetables cook slowly.
- Onions
- Add savoury depth and aroma that blend into the puree.
- Velouté
- Thickens the puree and gives it a smooth, coating consistency.
The step that matters
Stew gently for 3 hours. Low, slow heat softens the vegetables fully without scorching the butter and sugar, which would cause bitter, burnt flavours. Gentle heat also lets the mixture break down evenly for a smooth sieved puree.
Swap the carrot
How well each one fits the dish's main ingredients (butter, onion, sugar):
- Potatofits better
- Leekfits better
