Quince Marmalade
Ingredients
Directions
Prepare the pulp
Peel the quinces and place them in a preserving pan with enough water to just cover the bottom.
Stew gently until the fruit reduces to a pulp.
Pass the pulp through a fine sieve and weigh it.
Make and store the marmalade
Return the pulp to the pan, add the sugar, and cook gently until the marmalade sets quickly when tested on a cold plate.
Pour into jars, cover with paper brushed with egg white, and store.

What each ingredient does
- Quince pulp
- Provides the fruit body and natural pectin that help the marmalade thicken and set.
- Loaf or preserving sugar
- Sweetens the marmalade and, as it dissolves and concentrates, helps it gel and keeps it preserved.
The step that matters
Cooking the pulp with sugar until it sets. Cook gently and test on a cold plate: too little cooking leaves it runny, while overcooking can make it stiff, dull, or caramelised. Pectin and acid need the right sugar concentration to gel.
