I HIGHLY recommend San Francisco Baking Institute. I have taken all of their one-week courses on bread, pastry and viennoiserie over the course of three years. Like you, I started out thinking of opening up a bakery, but after taking several courses and seeing some fellow students open up bakeries, have decided against it. It truly is extremely hard work, and I was personally concerned that I would lose my passion for baking. Instead, I have a very small home-based business where I make various croissants for a couple of the coffee houses here in my home town. It's a great outlet for my passion, but not overwhelming! The teachers at SFBI are all terrific. Also, Michel Suas (the owner) also has a second business (TMB Baking) that sells baking equipment. They are extremely helpful to their students who wish to open up a bakery. They'll sit down and plan it all out with you -- what kind of equipment you'll need, etc. Good luck!!
