In a large saucepan, combine pear nectar, brown sugar, lemon juice, ginger, cloves, cinnamon pieces, and bay leaves.
Heat over low heat, stirring until the sugar dissolves, for around 15 minutes
Strain off spices, if desired.
Remove from heat and stir in whiskey
Serve in heatproof glasses or mugs and garnish with a few pear slices
Notes
When you’re making the mulled cider you can just add whiskey to your glass, rather than the pot. That way you can control the strength and reheat the cider without losing the alcohol.
