Yes, I have all three -- the standard rice flour/gum/hing/turmeric blend (powdered), the con trick "Hing whole / asafoetida whole" (which is actually a wheat flour/gum/hing blend, sold in chunks) and real 100% hing, also sold in chunks. The first two ("faux hing") are by Top-Op, the real deal by Planet Spices.
P.S. Planet Spices are currently offering 2,2kg of pure hing for USD 160.
