As a kid, I worked in Sutter's on Greenwich. I packed cookies. The cookie that you enjoyed so much was called a clam. All Sutter's cookies were entirely hand-made. I placed the raspberry filling on one half and then came back to top it with another half. The same clam shape was used with a plain dough where the narrow end was first dipped into chocolate and finished with crushed pistachios. These were known as a pistachio tip.
