Cut into the “Black Krim” I harvested the other night. Fully ripened. Was tasty. But I’m not sure it’s a Black Krim, after checking some images online. No “black” in this tomato at all. Mystery tomato.
Black Krim?
Red, not Black 
Compare to an actual Black Krim, found online:
Actual Black Krim (not from my garden)
Your tomato looks nothing like the black one. Hmmmm, I wonder what your tomato is? Any ideas out there?
