Ingredients:
- 1.5 kg fresh quince
- 750 ml filtered water
- 1 large organic lemon, zested and juiced (60ml juice)
- 1 whole vanilla bean, split and seeds scraped
- 600 g granulated cane sugar
Instructions:
- Prep the fruit. Peel and core the 1.5 kg fresh quince. Slice into 1/2 inch cubes or thin crescents. <small>Note: Work quickly or keep submerged in acidulated water to prevent browning.</small>
- Initial simmer. Combine the quince and 750 ml filtered water in your heavy pot. Cook over medium heat for 20 minutes until the fruit is tender when pierced with a paring knife.
- Prepare aromatics. Split the vanilla bean and scrape the seeds. Add both the seeds and the empty pod to the pot.
- Add acid. Pour in the lemon zest and 60ml lemon juice. The aroma will immediately turn bright and citrusy.
- Incorporate sugar. Stir in the 600 g granulated cane sugar. Reduce heat to low and stir constantly until the sugar crystals have completely dissolved.
- The long simmer. Cook uncovered for about 1 hours to 1 hours 15 mins. Maintain a gentle bubble — not a rolling boil.
- Monitor color. Watch for the transition. The syrup will move from clear to yellow, then orange, until it reaches a deep, glowing ruby red.
- Test the set. Drop a spoonful of syrup onto a frozen saucer. Wait 30 seconds, then push it with your finger. It should shatter into fine wrinkles on the surface.
- Finish. Remove the vanilla bean pod. Ladle the hot preserves into sterilized jars, leaving 1/4 inch of headspace.
- Seal. Process in a water bath for 10 minutes or store in the fridge once cooled.
