Help with controller and view

How about something like this:

<h2>Ingredients</h2>
<ul>
<%- for ingredient in @ingredients -%>
  <li><%= ingredient.name %>
    <ul>
    <%- for supplier in ingredient.suppliers -%>
      <li><%= supplier.name %></li>
    <%- end -%>
    </ul>
  </li>
<%- end -%>
</ul>

Of course you will probably want to dry this up a bit using partials
and include suppliers in your find statement so you are not hitting
the database for each ingredient.
