How to use hook_menu to create wildcard aliases to a normal node page
fwiw, I now did this different. I won't accept this as an answer, because it isnt. But this works as well in my case

function kitchen_url_inbound_alter(&amp;$path, $original_path, $path_language) {
    if (preg_match('|^your/recepies(/\w+)?|', $path, $matches)) {
        $path = 'your/recepies';
    }
}
