Again, a harbinger of summer in America are the arrival of stone fruits in the market, such as peaches, nectarines, and cherries. These are all botanically of the same genus, Prunus, which also means that they are amenable to all sorts of fun hybridizations (many of which are patented). Of course, stone fruits of other sorts are found elsewhere.
In the market, I found these curious green lychees. Despite their appearance, these fruit are quite ripe and ready to eat. What makes them distinctive is that they have been bred to have a dramatically smaller pit.
Although these are a consolation prize, apparently, as the real prize are the legendary seedless lychees (allegedly bred in Taiwan).
