Thanks for the clarigfication. You got me axcited since I have been looking for sources that say yo uneed two different foods and they are surprisingly few. the Aruch Hashulchan being a notable exception.
now this may be because it is obvious that “two portions”, have to be two different foods (otherwise could just cut piece of meat in 2 and call it 2 portions) But 2 steaks or 2 pineapples are certainly 2 portions. So im not sure why a person wouldnt be yotzei.
Interestingly in Mikrai kodesh R’ Frank says that two peices of meat from different parts of anaimal that taste different are a kosher shalach manso ( eg white and dark chicken?)
