I just had my first experiance with an iris today.
It is an Italian type donut (like a beignet) that is filled with oozing custard or ricotta, covered with bread crumbs and fried. It is a Sicilian pastry and this is supposedly the Catania version.
In Palermo they hollow out a stale roll, fill it, cover in bread crumbs and fry.
Here's a link to a recipe:
So, is this a common dessert? How do you make it? Who was Iris?
