Assuming you do make one that is. The sweet kind, to be specific.
Bread pudding is pretty basic at its core -- cubed bread, custard base, and maybe some sort of fruit (e.g. raisins or apples) -- but everyone has their variations or twists to make it special or unique.
A little alcohol like rum or bourbon?
Some exotic spices like cardamom, cinnamon, allspice, or whatever? Maybe even mint or peppercorns?
Perhaps you like it a bit more decadent with things like chocolate?
OR ditch the bread entirely and use something Paula Deen-ish like donuts?
What say you?
