Bonjour Paris reports the following recent ice cream creation by Herme: "Miss Gla Gla, Pierre Herme's take on the ice cream sandwich. This is no chocolate wafer with vanilla filling however. The Miss Gla Gla I tried swirls strawberry sorbet and cardomom ice cream with a touch of orange sauce, all sandwiched between two delicious wafers."
I have not yet sampled Ishpahan ice cream, modelled after the rose macaron/lychee pastry concoction of the same name by Herme.
The Herme shop is apparently closed for certain portions of August, though. Pierre Hermé, 72 rue Bonaparte, 6th. Metro: Saint Sulpice
