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 jam and give it body and natural sweetness once pureed.
Loaf sugar
Sweetens the jam and, as it cooks down, helps it thicken and set.
Lemons
Add acidity and aroma from the juice and rind, brightening the sweet carrot flavor.
Sweet almonds
Add fat and a nutty flavor and a little texture to the jam.

The step that matters

Boil all together for about an hour. The mixture must cook long enough for water to evaporate and sugar to concentrate, so the jam thickens and sets rather than staying runny.

Swap the carrot

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

  1. Arrowrootfits better
  2. Kalefits better
  3. Broccolifits better
  4. Carrotthe original

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