In my view, the red sauce preceding dessert isn't as important as matching the theme and ingredients of the meal.
For example, you have simple, basic, good ingredients with dinner, so match that with dessert. Bananas Foster would be good. I've served chocolate and lemon sorbet (Haagen-Dazs) together which went remarkably well, etc.
The other choice is to stick with the theme. You're serving Italian, so have canolies

Don't trial to reinvent the wheel. Them Ayetalians know what they're doing.
