找到了,https://en.wikipedia.org/wiki/Crataegus_mexicana
抄一段:
The fruit is eaten in Mexico cooked, raw, or canned. It resembles a crabapple, but it has three or sometimes more brown hard stones in the center. It is a main ingredient used in ponche, the traditional Mexican hot fruit punch that is served at Christmas time and on New Year's Eve.
它旁边的是番石榴,我们小时候是夏天暑假的时候满大街都是,很香很香的。不过今天店里看到的番石榴没有香味。
