Lovely Neighbor and Rhubarb?

I am so lucky to have great neighbors in my building in a big city like New York. My building has a variety of people - retired people to high profile professional people.
My favorite has been J. who is retired but very active - every day she has something on her calendar, e.g. museum, play, dinner with friends...

I ran into her on the way back from the gym. She mentioned about rhubarb last time we talked but this time she gave me her rhubarb source/filling - with strawberry along with orange zest and ginger (my guess). I don't recall I had this before, and it is very refreshing. I might try it with ice cream next time (if we run into again and she still has it for me). Thank you - J.
