There is a place on Coneticut around Dupont Circle for really, really great ice cream. My husband and I stop there several times each fall when we visit DC. The name of the place is Jerry's and they mke their own ice cream.
Every flavor that we have trie have been have been ammazing but the two that are our aabsolutes faves are the lychee which is mmande from FRESH lychee, not canned and our number one fave is the halva. OMG, it is sublime. It is made from tahini and honey and has sslivers of almonds for texture. This year we bought a tub and brought it back to Clevelaand with us to share with friends.
The shop closes for winter and will only be open for another two weeks or so.
