How to load a node based on current language?
Try this code:

 $node_trad = node_load($variables["node"]-&gt;nid); // in your case, 10.
 $idi_trad = translation_node_get_translations($node_trad-&gt;tnid);

  $vars['recipe_side'] = render(node_view(node_load($idi_trad["fr"]-&gt;nid)));
  //$vars['recipe_side'] = render(node_view(node_load($idi_trad[$language-&gt;language]-&gt;nid)));
  // alternative, more dynamical                


Essentialy you load the node in original language, use the translation function to get all available translations, and use that what you need.
Instead of "fr" you could use language-&gt;language instead to make it completely dynamical.
