How to Make It
In a medium saucepan, bring the wine, beet juice, sugar, lemon, cinnamon stick and 1/4 cup of the crème de cassis to a boil. Simmer over moderate heat for 5 minutes, stirring to dissolve the sugar. Add the pears, cover and simmer over moderately low heat, turning once, until just tender, 15 minutes. Using a slotted spoon, transfer the pears to a bowl.
Boil the poaching liquid over moderately high heat until reduced to 1 cup, 13 minutes. Stir in the remaining 1/4 cup of crème de cassis. Pour the syrup over the pears and let cool completely, then refrigerate until chilled, 30 minutes; discard the cinnamon stick.
Serve the pears with the syrup on a platter or in shallow bowls. Serve with vanilla ice cream.
