Change slug language

Hi there,

thank you for a very good plugin.
I would like to change the “recipe” in the slug to my own language. Ive tried to find it int he .po and .mo files but nothing. I know i can turn the slug off in advanced settings within the plugin, but I want to keep it, just change language. thank you
