Add the cherries to a large skillet over medium-low heat.
Stir in the sugar, lemon zest and lemon juice to combine.
Cook the cherries until the sugar dissolved, approximately 4 minutes.
Stir and increase the heat to medium-high. Continue cooking for an additional 5 minutes until the cherries become juice and the sauce starts to thicken slightly.
To flambe, remove the pan from the heat and add the bourbon or kirsch. Ignite the cherries with a long match or lighter.
Swirl the pan lightly until the flame burns out, approximately 20-30 seconds.
Scoop the ice cream into 4 dishes and spoon the cherries with the juice over the ice cream.
Serve immediately.
Notes
Cherries Jubilee is best served soon after cooking but leftovers can be stored in the refrigerator in an airtight container for up to 3 days. Reheat before serving.
