Custard apple or bullock's heart (น้อยหน่า)

don't call this fruit either custard apple or bullock's heart. Both names are utter nonsense. For the former, I can very well imagine how early European explorers were lost for words when they tasted this for the first time and picked up a word from their very limited frame of reference. For the latter, the bullock's heart, I just can't follow the line of associations. For me this fruit is forever Noy Naa. Removing the green scales with fingers, I love sinking my teeth into the white flesh that manages to be flaky, crumbly and juicy at the same time. It is full of black stones that are such a pleasure to spit out because they are so hard and slippery.
