You've found the Convergence Menu website, and the launching pad to the Convergence Menu application.

“It scales, it converts, it translates, it prints, it publishes.”

Put simply, ConvergenceMenu is a geeked-out, fully internationalized, user-submitted recipe library: it scales, it converts, it translates, it prints, it publishes. There's even advanced stuff such as event planning, shopping lists, and offline support (but that's mostly for bigger players). In essence, it's about putting food on the table. And it's also about putting lots of food on many tables. ConvergenceMenu is many things really, depending on your needs:

  • For the home user it's an online, multilingual recipe sharing platform.
  • For the meal-prepper, it's a recipe calculation tool and shopping list generator.
  • For the caterer or event planner, it's a tool for managing the administrative nightmare challenges surrounding meal planning and logistics of cooking for large groups.

Whoever you are, it's a place to keep and share your favourite recipes, and an easy way make attractive printouts, scaled to the number of mouths you have to feed. What's not to love?

What's new?

  • Fixed some issues with unit conversion behaving very weirdly in very specific situations.
  • Improved the unit converter page usability.
  • Several minor usability improvements and admin features in the back-end app.

Fixed a few minor things which were bothering me:

  • Included private units in unit selection when a unit-system preference is set (back-end)
  • Fixed an issue where the original image file was deleted when uploading images via the back-end desktop app.
  • Updated the recipes (and myrecipes) tables to highlight multilingual recipes.
  • Fixed issue where recipes shared in multiple recipe books were appearing multiple times in search results.

Being stuck at home during this crazy period of coronavirus isolation, I've had time to add something which has been on my list for a while: proper support for attributing credit. It's now possible to credit the source of your inspiration, and to even link to their website (which is a nice way to say thanks, and is good for their business and google ranking).

Other bugfixes & minor enhancements:

  • Placed click-able links in the recipe table, which lets you open them in new tabs (thx Kaja!) :)
  • Made translations appear correctly on the 'my recipes' table.
  • Fixed minor SEO issues

Also thanks to Nina for help with translations and idea-bouncing (as usual). :)

Due to the sheer scale of work required to implement multilingual support, this release has been a long time in the works. But now at long last, it's done! To start with, I've only added translations for Croatian to see how it goes (heartfelt thanks to my translating crew: punica Bise and žena Nina), and I'll add more languages later depending on the response I get. (BTW if you'd like the website to support your language, please get in touch! Especially if you're willing to help with translating it I'd love to hear from you!)

But the website translations are just the beginning. What's even cooler is multilingual support for the actual recipes themselves. This means a recipe can be entered in multiple languages, including not just its original text but also common languages (e.g. English, Spanish, etc). In this way it's possible to open traditional cooking to the world while preserving its authenticity.

And it's not just the recipe texts. Ingredients, units, and everything are translatable. The entire recipe can be switched to a different language without losing its meaning.

Other bugfixes & minor enhancements:

  • Implemented sending of e-mails
  • Added e-mail verification step for account sign-up
  • Cosmetic fixes for recipe display page and report
  • Fixed glitch converting between unit systems on unit conversion page
  • Fixed minor bug which hindered sharing from back-end.
  • Fixed structured data and added language tags for the google spider bot.
  • Minor irritating post-release bugfixes (v2.5.1).
  • Recipe presentation tweaks, back-end translation bugfixes, submission approval process fixes (v2.5.2).

Bugfixes & minor enhancements:

  • Fixed unit conversion scaling issue in recipe reports (oops!)
  • Redirects to user's recipe list after login (instead of account).
  • Fixed website recipe visibility issue with privately shared recipes
  • Fixed back-end recipe visibility issue for privately shared recipes.
  • Updated share-with-group option in back-end to disable groups where the recipe has already been shared.

This release contains only one feature, but oh, what a feature: Units conversion is here!

What this means, is that recipes can be converted between unit systems. So a recipe written in metric measures can be switched to UK or US imperial units (or whatever) directly from the website. Why is this cool? Because it's one less barrier preventing people of different cultures from sharing their recipes. Especially if you grew up in one of those weird places that use decagrams or fluid ounces. ;)

To be fair, it's not magic; it's strictly mass-to-mass or volume-to-volume (you need density to do mass-to-volume, and that's too crazy even for me - this was mind-bendy enough), and you need to relate it back to grams or milliliters. But hey, this is a big step even so.

I also linked up the user preferences (and made it editable from the website), so your preferred unit system is loaded by default. You can still use the original measures if you wish, and if you don't see a unit you'd like to cook with, you can just go and create your own.

  • Can search within a recipe book or your own personal recipe library (when logged in).
  • Also searches for recipes with related (i.e. more specific forms of) ingredients.
