  2. Cook until the vegetables are soft.

  3. Add stock and sugar, then stew gently for 3 hours.

  4. Pass the mixture through a tamis.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Carrots
Form the bulk of the puree and give it its flavour and body.
Butter
Adds richness and carries flavour while the vegetables soften.
Onions
Add savoury depth and sweetness as they cook down slowly.
Velouté
Thickens the puree and gives it a smooth, coating consistency.

The step that matters

Reducing a thin puree. Reducing on the fire evaporates excess water, so the puree thickens without extra flour. Reducing too far, or too gently, changes the texture and can scorch the bottom of the pan.

Swap the carrot

How well each one fits the dish's main ingredients (butter, onion, sugar):

  1. Potatofits better
  2. Leekfits better
  3. Chivefits better
  4. Carrotthe original

Fit is the average pairing score against butter, onion, sugar. Candidates are from the same food group and used in at least 100 recipes.
