Macedonian Jelly

Ingredients

Directions

Make the jelly

  1. Dissolve the gelatine in cold water and let it sit for 30 minutes.

  2. Heat the mixture gradually until melted, then add lemon juice and sugar.

  3. Stir in the beaten egg whites over low heat until it boils.

  4. Add a large spoonful of cold water and skim off the froth.

  5. Strain the mixture through a wet jelly bag.

Set with grapes

  1. Cool a small amount in a mold and place it on ice.

  2. Once set, layer in the grapes and more jelly, repeating until the mold is full.

  3. Finish with a layer of jelly on top and keep the remaining jelly warm.

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

What each ingredient does

Gelatine
Sets the liquid into a firm, sliceable jelly as it cools.
Egg whites
When heated they collect impurities, which are skimmed off, clearing the jelly.
Lemon juice
Adds acidity that brightens the flavour and balances the sugar.
Sugar
Adds sweetness and helps give the jelly a smooth, tender texture.
Malaga grapes
Provide the main fruit flavour and juicy texture suspended in the jelly.

The step that matters

Add the egg whites and bring to a boil gently. Egg whites must be stirred in over low heat so they coagulate and trap impurities rather than cooking into the liquid. Heating too fast or stirring unevenly leaves the jelly cloudy and harder to clarify when straining.

Swap the grape

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

  1. Orangefits better
  2. Vanillafits better
  3. Limefits better
  4. Grapethe original

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