Started my first ever business selling hotsauce! what licenses do I need in maryland? ( sauce is made in commercial kitchen )

Hey everyone,

I decided to kinda dive head first into my first ever business. I used a commercial kitchen sent them my recipe and ordered a case of hot sauce, super exciting! It's a chipotle pale ale sauce!

Anyway the sauce is shelf stable and FDA approved and the label is compliant because it was made with a Co-packer

My question is what else do I need? To sell in stores and farmers markets in the state of Maryland? Do I need my own LLC still? Do I need a EIN? Anyone with experience in this area would be awesome! Thanks!
