Italian Almond Brittle
Vendors along the streets of Bologna sell Brocante con Mandorle in large sheets. It can be made with toasted filberts also. In Italy they it is made with whole almonds and is very thick. It is very hard but delicious. I found that if you use sliced almonds it is a little thinner and a little easier to eat. The flavor is more intense with the whole almonds.
