Delicious Quince Jelly

Ingredients

Directions

Prepare the fruit

  1. Place chopped quinces and apples in a preserving pan and cover with water.

  2. Cover the pan and simmer for several hours.

  3. Drain the mixture in a colander overnight.

  4. The next morning, strain the juice through a jelly bag.

Make the jelly

  1. Measure the juice and add an equal amount of sugar, then boil until it turns pink.

  2. Test the consistency on a saucer; when thickened, dip the geranium sprigs in the jelly and swirl them.

  3. Remove the jelly from heat and pour it into glasses.

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

What each ingredient does

Quinces
Provide natural pectin and tart flavour that help the jelly set.
Apples
Add additional pectin, helping the juice gel firmly when cooked with sugar.
Sugar
Sweetens the jelly and, at high concentration, helps it set by binding water.

The step that matters

Testing the set on a saucer. Boiling must stop once the jelly thickens. Overcooking can make it stiff and dull, while undercooking leaves it runny, so a cold saucer test shows when it has reached setting point.

Swap the quince

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

  1. Vanillafits about as well
  2. Strawberryfits about as well
  3. Orangefits about as well
  4. Quincethe original

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