Step 1: Prep the Quince
Peel quince and cut into quarters (or halves if smaller).
Save the peels and seeds — they contain natural pectin and help the syrup develop a rosy hue and body.
Step 2: Poach
In a wide, heavy-bottomed saucepan, combine water, sweetener, cracked cardamom pods, vanilla, lemon zest, lemon juice, and quince peels/cores.
Add the quince quarters. Bring to a simmer over medium heat.
Cover with parchment or a lid slightly ajar and simmer gently for 60–75 minutes, until the quince is tender and rosy.
You can simmer longer (up to 90 min) for a deeper pink hue — depending on the variety.
Step 3: Strain & Reduce Syrup
Carefully remove quince and set aside.
Strain poaching liquid and discard solids.
Return liquid to pot and reduce over medium-high heat for 10–15 minutes until slightly thickened and glossy. Taste and adjust sweetness if needed.
Step 4: Serve
Serve quince warm with syrup spooned over, or chill for later use.
Optional: Add a dollop of whipped mascarpone, coconut cream, or serve atop low-carb yogurt or panna cotta.
Garnish with a cracked cardamom pod, rosemary tip, or pistachios.
