To Preserve Whole or Half Quinces
Ingredients
Directions
Prepare
Add sliced golden pippins to a pot of boiling water, cover, and boil quickly until the water thickens into jelly.
Scald the quinces.
Make the preserve
For each pint of pippin jelly, add one pound of sugar, boil, and skim until clear.
Add whole quinces to the syrup and boil rapidly; if using halved quinces, boil them separately.
Skim the syrup and test a small amount to see if it jellies before removing from heat.

What each ingredient does
- Golden pippins
- Their natural pectin and acid help the liquid thicken into a jelly that sets the preserve.
- Quinces
- They supply the fruit flavour and body, and their pectin adds to the setting of the syrup.
- Sugar
- It sweetens the preserve and, with boiling, concentrates the syrup so it can set.
The step that matters
Test for set before removing from heat. Pectin sets only at the right concentration of sugar, acid and heat. Removing the syrup too early leaves it runny, while cooking too long can make it stiff and dull.
