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

What each ingredient does

Guavas
Provide the main flavor and natural pectin that helps the jelly set.
Limes
Add acidity that brightens the flavor and supports pectin setting.
Sugar-candy
Provides sweetness and, as it concentrates during boiling, helps the jelly thicken and set.

The step that matters

Boil and skim to the reddish-brown color. Boiling evaporates water and concentrates sugar and pectin so the juice can gel. Stopping too early leaves it runny, while boiling too long darkens it further and can turn it bitter or scorch it.

Swap the lime

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

  1. Pineapplefits better
  2. Vanillafits better
  3. Mangofits better
  4. Limethe original

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