Thick Apple Jelly or Marmalade, for Entremets or Dessert Dishes

Oven, in the book's wordsA very slow oven

Ingredients

Directions

Make the marmalade

  1. Peel, core, and boil the apples with just enough water to prevent burning.

  2. Beat the apples into a pulp and cook for about 20 minutes until they no longer stick to the pan.

  3. Add the sugar and cook for an additional 20 minutes.

Set and serve

  1. Pour the jelly into water-dipped moulds and let it set.

  2. Serve with custard and garnish with strips of citron or blanched almonds.

    Shared aroma: 2-nonenal (fatty, green).

Apple and sugar barely smell alike, yet cooks put them together in 16,478 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

Apples
Provide the pectin and bulk that gel the marmalade as it cooks down into a pulp.
Sugar
Adds sweetness and helps the cooked apple mixture thicken and set into a firm jelly.

The step that matters

Cooking the apples into a pulp until they no longer stick to the pan. Apples need enough water and time to soften fully. Stopping early leaves a thin mash that will not set, while overcooking can scorch the bottom. Sugar is added only after the pulp is ready.

Swap the lemon

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

  1. Pearfits better
  2. Vanillafits better
  3. Apricotfits better
  4. Lemonthe original

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