In a medium saucepan, combine the cherries, water, lime juice, and sugar. Bring to a boil. Reduce the heat to medium-low and simmer for 15 minutes, stirring occasionally. In a small bowl, combine the cornstarch and kirsch and add to the cherry mixture. Return to a boil and cook for 1 minute, stirring. Reduce the heat to low and simmer until thickened, about 4 minutes. Serve warm with the Lime-Scented Scones and whipped cream.
