Flaming Pears

I thought I saw this recipe in a cookbook, but then I couldn't find it. So I kind of winged it.

For this, I used:
About 1 lb pears, peeled and sliced
2 tbsp organic butter
2 tbsp organic sugar
rum

1. Melt butter in skillet.
2. Add pears and sprinkle with sugar.
3. Cook, stirring occasionally, until pears are soft and liquid has evaporated, 10-20 minutes.
4.  Pour rum over pears, light on fire, and let the alcohol burn off.
5. Serve while hot, with ice cream or cream.
