Our mother starter was first cultured in San Francisco over 100 years ago. It has been fed continuously ever since, picking up the deep tang and complex flavor that classic San Francisco sourdough is famous for. Every Boca Dough loaf rises with this same culture.
When you order the kit, we pull a piece directly from the active mother, feed it, let it hit peak activity, then seal it for the trip. That means your starter shows up ready to bake - no months of building from scratch, the easiest way to get started making the best sourdough.

"Their sourdough bread is the best, moist and richly flavorful, not airy, perfect density. Their cookies are superb, wholesome flavor from excellent ingredients, naturally sweet, not sugary yet deeply satisfying. The best of baking. Excellent easy communication regarding pick up, and punctual."

"Tried every sourdough in town, and nothing compares to this delicious bread AND cookies. The bread was crunchy on the outside and warm and soft on the inside with a delicious taste. Cookies were soft and warm. I will be a returning customer every week. The convenience of ordering fresh bread and cookies for next day is a luxury!"

"Picked up a couple of loaves today and chocolate chip cookies and everything was really good. I won't be buying bread again at Publix when Boca Dough is so close. The best part is a hard working 10 year old with great work ethic starting a business."
- Jeffrey Govberg
"I was in Boca on an overnight business trip and wanted to gift some cookies. As soon as I read 'sourdough cookies' there was no need to look further. They accommodated my order on short notice - freshly baked and smelled heavenly. I gifted the cookies as planned and brought a few back to share with my office. Absolutely amazing and left us all wanting more!"
- Nikki Mitchell

"Cookies are chewy and decadent, and as healthy as one can get with the ingredients for the guilty pleasure. The bread is fresh, outstanding and addictive. No additives, just the basic ingredients. You will never find anything like this bread in a supermarket. Best part - super easy to buy and pick up!"
- Andrea Rodriguez
"Without exaggeration this was the best sourdough bread I ever ate. The fact that it was baked by 10 yr old Meilani out of her home with her family's support makes this an amazing story, but make no mistake, the bread is the star of the show. I highly recommend trying the bread. You will be hooked immediately."
- Bart Friedman
"Delicious! Best sourdough in all of Boca!"
