Recipes that travel with you

I want to tell you about the small idea that turned into the biggest feature in the app.

For years I've had a frustration with how recipes get shared. Someone says "send me your loaf recipe" and the options are bad: screenshot the photo, paste into a text message, hope they can read the handwriting, hope they don't lose the chat thread, hope they re-type it without mistakes.

Recipes deserve to be files. Like a PDF, like a song, like a photo. Something you can keep, edit, name, share.

So the app reads and writes a tiny format called .sourdoughrecipe. It holds the whole recipe — every gram, every step, every note. A few kilobytes. You can:

  • Download any of my 100 recipes as a .sourdoughrecipe from this site, tap it on your iPhone, and it lands in the app
  • Build your own in the app, export it, AirDrop it to a friend who has the app
  • Edit a friend's recipe, save your version, share it back

No accounts. No cloud lock-in. No "sign in to view this recipe." The recipe is a file, not an entry in someone else's database. It's yours.

This is the part of the app I'm proudest of, and the one I'm most excited for you to use.
