Chiming in to say pork rib soup with any vegetable is generally what I consider a simple + homey comfort soup. :') Seeing it in MDZS made me think, "oh, that checks out" even though I've never had that combination and never in a Chinese context... I can imagine how lotus root pork rib tastes, and I feel like I'd also like to try it if I have happen to have lotus root on hand! But I'd still want other vegetables to go with it, I think...
