I got this at the farmer market in Taiwan. This is around 2.5 inches in diameter, the shells is hard like a walnut and the exterior smells very garlicy. The guy who sold it to me told me to crack the nut open, slice and put it in chicken soup.
I am hoping to ID this before I proceed to crack this open to see the insides. SOOO curious!
Does any of you know what this is? What other uses besides chicken soup?
