Heat cream in a medium heavy saucepan over medium heat until bubbles appear around the edges; remove from heat. Add white morsels and whisk until melted and smooth. Stir in peach puree and then white chocolate liqueur. Transfer mixture to a fondue pot. To keep fondue warm at the table for an extended time period, place over a candle or a canned burner. For eating immediately, serve in a decorative gravy boat. Serve fondue with meringue cookies and dipping variations.
