CakePHP does not support composite primary keys. This has been
discussed at length. Just add an auto-incrementing column to your
table and make that the primary key [ change your primary key index to
a unique index first ].

Assuming food_id/category_id are unique, this will work fine:
$this->FoodCategory->deleteAll(array('food_id' => 1, 'category_id' =>
3), true, true);
(If they're not unique this may delete more than one row)
> Cake requires a single primary key "id".
Well, you don't have to call it "id". Just set the `$primaryKey`
member variable (in the model) to the name of the primary key.
