Quince Jelly

I'm lucky to often get quinces. I went in search of a recipe to make jelly yesterday and found this on lynwood preserves. I made a recipe and a half and am posting that version here. Prep time doesn't include the time taken to strain the liquid initially.

• Ready In: 1 hr
• Yields: 2 litres

Ingredients

• 3  kg  ripe quinces
•  caster sugar
• 3  large lemons
• 3  liters water (or enough water to cover the quinces)

Directions

1. Wash the quinces, scourer off the down, and then quarter them roughly. Put the cut up quince into a preserving pan with the water and simmer long and slowly until they become soft. It can take over an hour to reduce well.
2. Strain through a jelly bag overnight (by jelly bag, I mean a tea towel or very fine sieve – whatever you have at your disposal that fits within that criteria will be fine). Do not force the juice, as it will make it cloudy.
3. Measure the juice into the preserving pan, and for each 600 mls of juice add 375g caster sugar. Bring juice to simmering point, add the sugar and the strained lemon juice. Dissolve over a very low heat. Boil fast and begin testing for a set after 10 minutes. When soft set is reached, pour into small, sterislised, hot jars and seal.
4. This jelly stiffens during storage, and looks like a ruby jewel in the jar. It is delicious is served with lamb or boiled or baked pork, or simply as jelly with toast and butter for breakfast.
