Recipe was a sweet module.
Exports in RecipeML, calculations...
and it looks like it's back!
Recipe is a module for sharing cooking recipes. It provides a Recipe content type, an Ingredient entity type, an Ingredient reference field, and custom Views display styles for recipe sharing and printing.
Recipe is one of the oldest contrib modules! The first lines of code were written in 2002. Check out the CHANGELOG.txt file for a glance into Drupal's early history.
It's installed, but there are issues. Like the titles. ;)
