I certainly agree with the passion part, but there’s also a business aspect to consider. When I wanted to start my own cake business, I quit my “big girl job” and got a job at a local pastry kitchen. I learned so much, not only about pastries, baking, and decorating, but about the business aspects as well. They worked me like a dog, but they did allow me to use their kitchen to sell my own cakes on the side. I finally decided that a retail shop was not for me and went through the process of building a legal kitchen on to my house. The laws in each state are all very different if you decide to go the home-based route. Some make it really easy, some make it impossible.
Which ever way to decide to go, I wish you the best!
