In a heavy-bottomed saucepan over medium-high heat, combine water, Calvados, and sugar. Cook, whisking often, until sugar dissolves. Increase heat to high, and bring mixture to a boil. Continue cooking until sugar mixture reaches 280° on an instant-read candy thermometer and caramelizes. Remove from heat.
Add butter, and whisk until combined. Add cream, whisking to combine.
Add apples to pan, and return pan to stove top. Cook over medium heat for about 20 minutes, or until tender, turning apples occasionally. Serve with reserved caramel and Apple-Brandy Sabayon. Garnish with almonds and mint, if desired.
