An open source recipe is one you are explicitly allowed to reuse, adapt and share, because it is in the public domain or carries an open license such as Creative Commons. A recipe that is merely free to read online does not qualify. This guide shows how to tell the difference, where to find genuinely open recipes and cookbooks, and how to credit the original when you publish your own version.
RecipeforkAdapt Recipes, Keep Their Origins ConnectedRecipeFork lets home cooks share adaptations, credit original recipes, and collect favorite versions in personalized cookbooks.Explore RecipeForkThe phrase borrows from software, where source code is published under a license that lets others study, change and redistribute it. For food, the same logic applies to the written recipe: the title, the ingredient list, the method and the notes. If the author has said, in a license or a public-domain dedication, that you may reuse and modify it, it is open. If they have not, you are guessing.
That matters because the law is less simple than many cooks assume. According to the USENET Cookbook, copyright generally protects the specific written instructions of a recipe but not the underlying functional formula, and rewriting a recipe in your own words can avoid infringing the expression. In practice, though, a community that wants to share recipes safely needs a clearer rule than “I changed a few words.” As one open source community essay on crowd-sourcing cookbooks points out, a recipe passed around at a potluck may secretly come from a restrictively copyrighted book, and republishing it can cause trouble.
This article is about the recipes themselves, not about apps. If you are looking for self-hosted programs that store and organize your recipe collection, that is a separate category: software can be open source while every recipe inside it is still someone else’s copyrighted text. Keep the two ideas apart, because a free app never grants you rights to the content you put in it.

A few kinds of places publish recipes you can build on.
The best-known example is the Cookbook project on Wikibooks. Its Cookbook FAQ explains that contributors may add recipes only when they own the rights, or when the source is in the public domain. Contributors are also asked to write in their own words rather than copy modern recipe text, and to cook and assess any AI-generated recipe personally before adding it. Those rules make it a sound starting point when you need material you can legitimately remix.
Smaller communities do the same thing for their own niches. The Koha library software community keeps a cookbook of how-to recipes where contributors submit entries through GitLab forks and merge requests, and the team checks submissions for errors before merging. It is not about food, but it shows the model clearly: fork, change, review, merge, with every contribution traceable.

Open Recipes is an open database of recipe bookmarks. It deliberately leaves out preparation instructions and sends you to the original publisher for those, and it provides regular JSON snapshots in a format that mirrors the schema.org Recipe type. That makes it useful for developers and for discovery, but not as a source of method text you can republish. Do not confuse it with other projects that have similar names; read each project’s own about page.
Old cookbooks whose copyright has expired are a rich source of public-domain recipes, and your own family recipes are yours to share. Both are open in practice: you can adapt, republish and credit them as you like. The USENET Cookbook is a historical example of this spirit. It was a worldwide community database whose users could customize it by selecting recipes and adding their own, with a moderator who approved and edited submissions for style, form and content.
On RecipeFork, cooks can discover recipes, adapt them (we call it forking) and collect their favorites into personal cookbooks. Every fork stays connected to the recipe it came from, so credit travels with the dish. That is a different thing from a formal open license, and we will come back to how the two fit together below.
Use this quick check before you copy, adapt or republish anything.
A material is genuinely reusable when it is explicitly licensed under terms like Creative Commons, which set conditions for attribution, commercial use, modification and sharing, as a public library’s copyright guide explains.
Creative Commons licenses are built from four components: Attribution (BY), ShareAlike (SA), NonCommercial (NC) and NoDerivatives (ND). Combined, they make six distinct licenses. Here is what each component means for a cook.
| Component | What it requires or bars | What it means in your kitchen |
|---|---|---|
| BY (Attribution) | You must credit the creator | Name the author and link back when you share |
| SA (ShareAlike) | Adaptations carry the same terms | Your tweaked version must use the same or a compatible license |
| NC (NonCommercial) | No commercial use | Fine for a family cookbook, not for a book you sell |
| ND (NoDerivatives) | No modifications | You can share it as written, but not publish your own variation |
The summary above follows the same library guide. Two practical consequences follow.
ND recipes are a dead end for adapting. If you want to fork a recipe and publish your version, an ND license does not allow it.
SA recipes keep the chain open. The CC BY-SA 4.0 legal code says that when you share adapted material you must retain the creator and license information, link to the source where reasonably practicable, indicate that you modified it, and license your adaptation under CC BY-SA 4.0 or a compatible license. Everyone downstream gets the same freedoms you did.
For a fuller treatment, the legal code is the final word. If you plan to sell a cookbook, or if a license is unclear, ask a copyright attorney rather than relying on a general guide like this one.
For Creative Commons reuse, the baseline is to give the creator a reasonable form of attribution. For recipes, a good credit line has four parts:
For example: “Adapted from Grandma Rosa’s Tomato Sauce by Rosa Bianchi (CC BY-SA 4.0). I halved the sugar and added smoked paprika.” (This is an illustration, not a real recipe.)
The change note is not decoration. Under BY-SA you must indicate modifications, and even outside any license it is how readers learn what works. If your cousin’s chili calls for two teaspoons of cayenne and yours calls for one, someone cooking from your page deserves to know why.
We built RecipeFork on a simple observation: recipes have always evolved. Someone makes a dish, someone else swaps an ingredient, a third person scales it for a crowd, and eventually nobody remembers who started it. Traditional recipe sites tend to treat each page as a finished, isolated product surrounded by ads. We wanted the opposite: a place where a recipe is a living thing with a visible lineage.
That is why forking sits at the center of the platform. When you adapt a recipe, you credit the original and add your own twist, and the connection between the two stays visible. We think this does what a good open license does in spirit: it makes credit automatic rather than optional. It does not replace a formal license, and we would not tell you it does. If a recipe you want to share came from a book with all rights reserved, rewrite it from scratch or choose another.
We also believe in keeping the source of a recipe attached to your personal copy. A cookbook of favorites is far more useful when each entry tells you who made it first and what you changed since.

Collecting open recipes only helps if you can find them again and trust them. Guides on digital recipe organizing agree on a few habits:
These are practical tips from product guides, not rules, but they match what careful cookbook editors do. A recipe with an unknown origin and a mystery change is a recipe you cannot fully rely on.
If you have a distinctive or elevated dish you want to share, do it in a way that keeps everyone’s permissions intact.
A good example of how a family-sized collection can look is the set of recipes on our official RecipeFork profile, or a single dish like this roasted red pepper soup, which you can fork and make your own.
If you want a place to collect, adapt and share recipes with the credit chain intact, RecipeFork was made for that. You can browse public recipes, fork the ones you like, and gather your versions into personal cookbooks, without traditional ads getting in the way. Premium subscriptions add advanced recipe management and cookbook customization for cooks who want more.

Create your first cookbook on RecipeFork and start with a recipe you love, a note about where it came from, and your own twist.
No. Open source recipe software is a program whose code is public, often something you host yourself to store and organize recipes. Open source recipes are the recipes themselves, with a license or public-domain status that lets you reuse and adapt them. You can store copyrighted recipes in open source software, and you can keep open recipes in any app.
Not automatically. Copyright generally protects the written expression of a recipe, not the underlying formula, according to the USENET Cookbook. So copying the text of a website recipe is risky, while cooking it and writing your own description is generally treated differently. For anything you plan to publish or sell, check the license or consult an attorney.
It means you may share and adapt the recipe if you credit the creator, say you changed it, and release your version under the same or a compatible license. The terms are set out in the official legal code. It allows commercial use unless an NC element is added.
Start with the community-written Cookbook on Wikibooks for recipes contributors have the right to share. Public-domain vintage cookbooks and your own family recipes are other safe sources. You can also build one yourself in a shared RecipeFork cookbook.
Name the creator, link to the original, state the license if there is one, and add a short note about what you changed. That satisfies the attribution expectations of Creative Commons reuse and helps readers trust your version.
