Three Factors That Determine Safety
Food scientists use three primary measurements to assess whether a product can be stored safely at room temperature without supporting the growth of harmful bacteria. Understanding these helps you know where your product stands — and why the cottage food rules are drawn where they are.
Florida Uses the TCS Standard — Not a pH Rule
Florida statute §500.80 does not name a specific pH or Aw threshold. Instead, it prohibits "Time/Temperature Controlled for Safety" (TCS) foods — defined by FDACS rule as any food that requires temperature control to prevent the growth of harmful microorganisms or toxins. This is a practical, outcome-based standard rather than a lab-measurement requirement.
What this means in practice: if your product can sit safely at room temperature for its expected shelf life without spoiling or becoming unsafe, it likely qualifies. Jams and jellies pass because the combination of high sugar, high acid, and heat processing creates genuine shelf stability. Pickles and hot sauce fail because they are acidified foods — their safety depends on controlled acidification that cannot be verified in a home kitchen environment.
Most products Florida sellers want to make are naturally shelf-stable
Baked goods have low water activity. Jams and jellies have high sugar and acid. Dried spices, granola, nuts, and candy are all shelf-stable by nature. The vast majority of what home food entrepreneurs in Florida want to sell falls comfortably within the allowed category — the prohibitions are targeted at specific high-risk product types, not a broad restriction on home food production.
Allowed & Prohibited Sales Channels
Florida's 2021 "Home Sweet Home Act" expanded sales channels significantly. Here's where shelf-stable cottage food products can legally be sold and delivered.
Shelf Stability Deep Dive
For each major cottage food category, here's why the product is shelf-stable, what the rules are, and what edge cases sellers need to watch.
Baked goods are shelf-stable because the baking process drives off free water, reducing water activity to levels where bacterial growth is not supported. A properly baked cookie, bread loaf, or unfilled cake can sit safely at room temperature for days to weeks depending on the product. This is the largest and most flexible category in Florida's cottage food law.
- Fillings and frostings must be shelf-stable. Standard buttercream (butter + powdered sugar) is shelf-stable. Cream cheese frosting, custard, whipped cream, and ganache with high dairy content require refrigeration — prohibited.
- Fresh fruit cannot be used as a garnish or decoration on the finished product. Homegrown or fresh fruit incorporated into the batter and fully baked is acceptable.
- Home-canned fillings (canned pumpkin you processed yourself at home) cannot be used. Commercially canned pumpkin, pie filling, or fruit is acceptable as a baked-in ingredient.
- One stove or oven rule applies — must be a standard residential appliance. Commercial-grade ovens are prohibited.
- Pumpkin pie, sweet potato pie, and other low-acid vegetable pies are prohibited regardless of how they are processed at home.
- Focaccia with embedded vegetables or cheese is allowed — vegetables and cheese are incorporated into the bread, not applied fresh on top.
Jams and jellies are among the most popular cottage food products in Florida, and for good reason — the science of their preservation is well understood and reliable. The combination of high sugar concentration (typically 60–68° Brix), natural fruit acid, pectin gel structure, and heat processing during cooking creates a product that is genuinely shelf-stable at room temperature. This is why jams and jellies are nearly universally allowed across all U.S. cottage food laws.
- Must be fruit-based. Jams and jellies made from fruits — including citrus, berries, stone fruits, and tropical fruits — are allowed. Vegetable-primary products (pepper jelly is a gray area — see Special Categories) need careful assessment.
- Fruit butters are allowed when made from fruit (apple butter, peach butter, plum butter, citrus curd in some interpretations). Pumpkin butter and other vegetable butters are explicitly prohibited.
- Must meet standard jam/jelly definitions. The sugar and acid ratios that define a proper jam or jelly are also what create its shelf stability. Products with reduced sugar may not be shelf-stable and may not meet the standard definition.
- Chutneys and savory fruit sauces are typically prohibited — they fall into the acidified condiment category that requires commercial processing controls.
- Marmalades (citrus-based, high-sugar) are allowed.
Sugar-based confections are shelf-stable because high sugar concentration creates an environment inhospitable to microbial growth. Hard candies, brittles, fudge, caramels, and toffee all achieve stability through their sugar chemistry. Chocolate is stable at room temperature due to its fat content and low free water. Marshmallows are stable due to high sugar and low water activity.
- Caramels and toffee are shelf-stable when made with standard high-sugar formulas. Soft caramels with high cream content may have higher water activity — assess shelf life carefully.
- Chocolate-covered items are allowed when the base item is shelf-stable (chocolate-covered pretzels, nuts, dried fruit, graham crackers). Chocolate-covered fresh strawberries require refrigeration — prohibited.
- Truffles: dark chocolate ganache with low cream-to-chocolate ratios can be shelf-stable for short periods. High-cream truffles require refrigeration. When in doubt, test and consult FDACS.
- Fudge is generally shelf-stable and is one of Florida's most popular cottage food products.
Dried spices and herbs have water activity values well below 0.6, making them among the most inherently shelf-stable food products in existence. Spice blends, BBQ rubs, seasoning salts, finishing salts, and herb blends are all well within Florida's allowed category. This is a strong product category for Florida sellers given the state's strong BBQ, Caribbean, and Latin culinary traditions.
- Must be fully dried. Fresh herb blends or wet spice pastes are not shelf-stable.
- Infused oils are prohibited — oil creates a low-oxygen, low-acid environment that can support Clostridium botulinum growth.
- Seasoning packets and dry rubs for BBQ, jerk, or adobo-style blends are all allowed.
- Flavored salts (smoked salt, citrus salt, herb salt) are allowed — salt itself has extremely low water activity.
Dried snacks and baking mixes are shelf-stable because they contain very little free water. Granola baked to a dry crisp, trail mixes, dried fruit combinations, roasted nuts, and shelf-stable nut butters (no added water or dairy) all qualify. Baking mixes — the dry ingredients assembled for someone else to bake — are a strong cottage food category, especially pancake mix, cookie mix, and bread mix.
- Granola must be fully baked and dried — not a raw granola product with high moisture.
- Nut butters are allowed when they are shelf-stable formulations (no added water, no dairy). Most standard peanut and almond butters with oil qualify.
- Dry pasta (uncooked) is allowed. Prepared pasta dishes, pasta sauces, or fresh pasta are not.
- Baking mixes must be the dry product only — not the prepared baked good (that would be covered under baked goods rules).
- Dried fruit can be used in mixes and trail mixes. Freeze-dried fruit is allowed. Fresh fruit in snack mixes is prohibited.
Low-sugar and reduced-sugar products need extra scrutiny
Products marketed as "low sugar" or "sugar-free" may not achieve the same shelf stability as their standard counterparts. In jams and jellies especially, the sugar is not just for sweetness — it is what creates the shelf-stable water activity level. If you reformulate a product to reduce sugar, re-evaluate its shelf stability carefully before selling it as a cottage food product. FDACS does not review or pre-approve labels, so the responsibility for product safety rests entirely with the seller.
