New Jersey's cottage food rules permit 18+ categories of shelf-stable home-made food. Here's exactly what's open, what's restricted, and what's off the table.
Every food product on earth falls into one of two camps when it comes to safety: those that need temperature control to stay safe (called TCS foods), and those that don't (non-TCS). New Jersey's cottage food rules draw the line squarely between these two categories.
Non-TCS foods — shelf-stable items like properly dried pasta, baked cookies, or fruit jam with enough sugar — don't create conditions where dangerous bacteria can grow at room temperature. That's why they're permitted from a home kitchen, where food safety is harder to formally verify.
TCS foods require time and temperature control (refrigeration, hot-holding, or careful processing) to stay safe. Anything with fresh dairy, raw eggs, meat, or fermented beverages falls here. Selling these products requires a fully licensed and inspected commercial kitchen — not because the NJ Department of Health doubts your skills, but because the public health stakes are higher.
New Jersey also requires that all ingredients come from licensed, inspected sources. You cannot use home-grown herbs from your garden, foraged mushrooms, or fruit picked from your backyard tree — even if the final product would otherwise be shelf-stable. Every ingredient must be traceable to a licensed facility.
