Peel the pears: Peel the four pears, leaving the stalks intact.
Prepare the poaching liquid: Combine all the ingredients in a saucepan with 1 litre of water and bring to a gentle simmer.
Cover the pears: Place a lid with a small steam hole over the saucepan to prevent the exposed parts of the pears from drying out. A standard lid can also be used, although the liquid will take slightly longer to reduce later.
Make a cartouche, if preferred: Cut a round of baking parchment that fits inside the saucepan, then cut a smaller hole in the centre to allow steam to escape. Place it directly over the pears.
Poach the pears: Gently poach the pears for approximately 20 minutes.
Cool and steep: Remove the saucepan from the heat and allow the pears to cool in the poaching liquid. Refrigerate them overnight, if possible, so they can absorb the flavours of the syrup.
Bring to room temperature: Before serving, remove the pears from the poaching liquid and set them aside to come to room temperature.
Strain the liquid: Remove the pears with a slotted spoon and strain the spices from the poaching liquid.
Reduce the syrup: Cook the strained liquid over medium-high heat until it has reduced by approximately half, to around 300 ml, and has thickened into a syrup.
Serve: Drizzle approximately two tablespoons of the reduced syrup over each pear, then serve with fresh cream, ice cream or chocolate sauce.
Use any leftover syrup: Drizzle it over yoghurt, porridge or pancakes, or use it to moisten cake layers during assembly and frosting.
