I have never smoked a beef rib. Is there anything different than cooking pork ribs?
Rub, smoke temp, smoke time, internal temp?
IMO, yes - low(close to 200 as you can stay), slow(can't rush or go over 225 - they'll dry out), and long(4+ hours).
In/on BEEF rib rubs, I use no sugars and use black peppers only (no paprika/ceyenne).
There is no 'internal temp' to attain or worry about (as in raw pork); the key is to not 'burn' the moisture out of the beef!
