As soon as you peel the pears, rub them with lemon juice for flavor and so they won't get brown spots;
In a saucepan over low heat, add the red wine, sugar, cinnamon, cloves and lemon slices. Simmer, stirring occasionally, until sugar dissolves completely;
Keep sauce in simmer for 15 minutes;
Add the pears and continue simmering for another 15 minutes (for firm pears. Longer if you want softer pears), turning the pears around in the sauce to ensure even coloring;
If possible, it's better to leave the pears in the syrup overnight;
To serve, place the pears in individual plates, warm the syrup and drizzle over the pears. You may add a scoop of vanilla ice cream if you wish.
