Yes, for those who knows the tradition of BKT.
For generations, it is pork ribs soup.
And nothing else

I have not eaten beef kut teh or mutton kut teh but I don't think I would need a leap of imagination to know that the taste will be so different that these two would become two different dishes which ain't bak kut teh as it should be.

Bak kut teh must be cooked with pork ribs. Non negotiable.
