I am hoping to open a rum cake business. I am not rich and don't have
alot of money to do this. How can I start this business? I have never
done this before? Also, what is the best rum to use for a medium to
strong tasting rum cake without using the most expensive rum?

Hello Gigi. Starting and operating a business is a very complicated
venture indeed. Rather than write out a business plan for you which
would be impossible given that this is a $15 question and I don't know
the details of what exactly you are trying to accomplish, I will give
you a list of resources on starting up a small business that you wil
find very useful.

For rum my personal favorite is Captain Morgan although for a cheaper,
but still good Rum I would go for Ron Rico.
Wishing you the best in your business venture!
