Warm Cinnamon Caramel Sauce

In a medium heavy saucepan, mix water and sugar and then place on medium high heat. Allow to boil (without stirring; only swirl pan if needed) until pale golden brown, approximately seven minutes. (Watch closely; sugar burns quickly.) Remove from heat, and add butter and cream, while stirring vigorously (mixture will bubble). Return to heat and bring to boil and then remove from heat. Stir in vanilla, cinnamon, and salt. Allow to cool a few minutes before using. Serving Suggestion: Drizzle over Quick Cinnamon Apple Tart topped with vanilla ice cream.
