The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Gelatin
Sets the liquid into a firm, sliceable jelly as it cools.
Lemon juice
Adds acidity that brightens the flavour and balances the sugar.
Granulated sugar
Sweetens the jelly and balances the acidity of the citrus and juices.
Oranges
Provide fresh citrus flavour and juicy texture in the set jelly.
Pineapple
Adds sweet, tangy fruit flavour and juicy pieces throughout the jelly.

The step that matters

Wait until the jelly is nearly firm before stirring in the fruit. If the gelatin is still liquid, the fruit sinks to the bottom instead of staying suspended. If it has already set firmly, the fruit will not distribute evenly and the layers may not bond well.

Swap the pineapple

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

  1. Vanillafits better
  2. Limefits better
  3. Mangofits about as well
  4. Pineapplethe original

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