This is a rich, luxurious tart because both the caramel and ganache are very indulgent. Ideally, a 9-inch tart will make 9 slices. But in this case, I usually make no less than 12. For our family, it can make about 14 to 16 servings. Ziv and me, usually share a single slice, while Aadi does manage to eat a whole slice.
