I've looked on the net, so let me turn to Fandom Collected: I bought an herb at the Vietnamese/Cambodian grocery store a few blocks from here. It's labeled "E. Tu". At first, Carole thought it was cilantro; looks pretty similar. Long green stems and small leaves. Came in a packet about 8" long in shrink wrap with a base to hold the shape. Not as pungent as cilantro, but definitely tasty.
