Share a Slice of Togetherness: The key ingredient of any holiday is sharing delicious moments with those gathered around the table. Open a Bauducco panettone and share a slice of togetherness. 52 Hour Making Natural Yeast Fermentation: The secret ingredient which makes panettone so fluffy and delicious is the mother dough that Mr. Bauducco brought from Italy in 1950's. As part of our traditional, 52-hour process to make each loaf, our bakers save a bit of this mother dough every day to mix into tomorrow's batch, which is what creates our panettone's special flavor. Taste the tradition in every bite. Delicious recipes. Italian family tradition. Special baking process. What is panettone.
