Mary Berry’s quince jelly is a traditional preserve made by cooking quinces with water, extracting their juice, and simmering it with sugar until it thickens into a clear, amber-pink jelly. It slices cleanly, sets beautifully, and offers a sweet, slightly tangy flavor with hints of pear and rose.
1.5 kg fresh quinces
Water (enough to cover the quinces)
Granulated sugar (equal weight to strained juice)
Juice of 1 lemon (optional, for brightness)
Wash the quinces thoroughly to remove any fuzz. Chop into chunks—no need to peel or core.
Place chopped quinces in a saucepan and add enough water to cover.
Cook for 1–1.5 hours until the quinces are very soft and pale pink.
Pour the mixture into a jelly bag or muslin cloth suspended over a bowl. Let it drip overnight without squeezing to keep the jelly clear.
Weigh the strained juice and add an equal weight of sugar.
Return the juice and sugar to the pan. Stir over low heat until the sugar dissolves.
Increase to a rolling boil and cook until the jelly reaches 105°C (221°F) or passes the wrinkle test on a cold plate.
Skim off foam for clarity. Pour hot jelly into sterilized jars and seal immediately.
Allow the jars to cool, then store in a cool, dark place for long-term keeping.
