                 ^^^^^^^^^^^^^^

There is no C entity called 'sausage' defined in dishes.pxd.

If sausage is a C function or extension type, you'll need
to declare it in dishes.pxd. If it's a Python attribute,
you'll need to import dishes as well as cimporting it,
since a cimport doesn't imply a Python import.
