How to Make It
In a large saucepan, combine the red wine with the sugar and the orange and lemon zests. Put the spices in a tea ball and add to the saucepan. Bring the wine to a very slow simmer over moderate heat, stirring to dissolve the sugar. Remove from the heat, discard the tea ball and stir in the kirsch. Ladle the spiced wine into heatproof glasses and serve at once.
