This page needs JavaScript

The recipe checker runs entirely in your browser, so it needs JavaScript switched on. If you would rather not, you can read the conversion guide and send your recipe as an issue instead.

Bring your recipe

Recipes here are written in CKL, a notation that insists on real numbers — no "a pinch", no "until golden". An AI assistant does that translation for you, and asks you about anything your recipe leaves vague.

Use the assistant you already have

Works with ChatGPT, Claude, Gemini, or anything else that reads images and PDFs. Nothing to sign up for, and nothing is sent from this page.

Copy the instructions below.
Paste them into a new chat, then add your recipe — type it, paste it, or attach a photo or PDF.
Answer the questions it asks. It will hand back a finished recipe file.
Paste that file into step 2.

Send it in

Your recipe goes in as a pull request, which a maintainer reads before it appears on the site. GitHub handles the git part — you will not touch a command line.

Press Open the pull request. If you are not signed in to GitHub, it will ask you to — an account is free.
GitHub shows your recipe in an editor with everything already filled in. Scroll down.
Press Propose new file, then Create pull request. That is the whole thing.

Open the pull request

No GitHub account and not planning to get one? Send it as an issue and someone will open the pull request for you.
