Peel and core the pears. Cut them into quarters.
Place the pears in a saucepan and add the wine and sugar. Peel the lemon and cut the peel into very fine julienne strips. Reserve the lemon for another use.
Add the peel to the saucepan with cinnamon, cloves, and vanilla. Bring to the boil and simmer for 5 to 10 minutes, or until pears are tender.
Transfer the pears and the lemon peel to a serving dish.
Bring the liquid in the saucepan to the boil.
Reduce to half or until liquid becomes syrupy. Pour the sauce over the pears.
Let cool and chill.
