Panini di Sant'Antonio is a traditional soft bread bun originating from Tuscany. It's made with a combination of flour, milk, sugar, oil, eggs, yeast, salt, and a bit of rum. The dough is rolled into balls which are then brushed with egg wash and baked until golden brown.
Once baked, these buns are brushed with a syrup consisting of sugar and water. These sweet bread buns are traditionally taken to church to be blessed, and in the past these buns were blessed than distributed to the peasants as a sign of protection of Saint Anthony.
