A number of states prohibit the sale of any agricultural products without a license. Contact your local government to see whether it has those restrictions and, if so, how to apply for a license.

Also speak with a commercial insurance broker, as this kind of activity may be considered "business activity" not covered by your homeowner's insurance. For example, if you sell someone a putrid pepper and he or she becomes gravely ill and sues you, you want to be sure you're protected.
