We're going to build a TiddlyWiki edition to hold users' recipes.

In priority order:

- A recipe should be extremely easy to read and follow along.

- The list of recipes should be searchable, browseable, and filterable. Finding
  "Grandma Merritt's Chocolate Cake" should be trivial, but I should also be
  able to look at all desserts, find recipes that use "baker's chocolate", and
  to filter the list of desserts to those mentioning "chocolate".
   
- Tags like "Dessert" should be easily extensible/replaceable for the users
  needs.

- A recipe should also be easy to write.  If we can work out a parser for
  ingredients, it would help, but that may be overkill.

- It must work at mobile sizes.  Users will likely be viewing these when cooking
  on a phone or a tablet.

- There should be at least one view of the recipe that shows the ingredient list
  and the steps side-by-side, independently scrollable.

- It would be nice to have a step-by-step view, with the current step strongly
  emphasized in context (something like selected font-size: 150% and perhaps a
  distinct border, while nonselected have opacity of 40%.  Not these specific
  values but something that would let us easily see both context and current
  status.)
