There are some food safety and legal requirements that will help to create a delicious and safe product. This fact sheet, developed from New Hampshire Food Protection Section guidance, can help to get you started. In Parts One (https://extension.unh.edu/resources/files/Resource008106_Rep11826.pdf) and Two (https://extension.unh.edu/resources/files/Resource008107_Rep11827.pdf) you learned about the kinds of foods you can make and sell in your home kitchen.
