Prepare your poaching liquid. Measure the water, wine, and sugar into a saucepan and place on the stove over medium-high heat, stirring so that the sugar dissolves into the liquid.
Add flavors and spices, like vanilla, lemon peel, and cinnamon, and bring the pear poaching syrup to a very gentle simmer. Do not boil.
Peel and core the pears and add them to the poaching liquid. Cover with a cartouche and cook at a very gentle simmer, monitoring the heat as necessarey.
Poach pears for 20-30 minutes until they are tender when you test the base with a sharp knife.
Remove pears from liquid with a slotted spoon to a clean tray lined with kitchen paper and allow them to cool completely, or serve warm.
Store poached pears covered in the fridge or in an airtight container.
