While on our second tour of old town Quito, we visited an artisan store, built into the tunnels of the eldest church in 'old town' (1500s) and there on a shelf was Rhubarb Jam!
As a Canadian Girl, I love rhubarb, growing it, eating it and creating fabulous desserts with it. It was one of the few things I miss moving to Ecuador. (and regular supplies of blueberries).
Anyways, outside the church (look to the right side of the church pic), you will see little doors. These are shops built into the old tunnels of the church. (this pic I found on the internet as it shows the doors to the tunnels)
I have one view inside the 'Tunnel Tienda'. It was much like a maze of hallways leading into openings where some of the coolest local artisan can be purchased. The items line the tunnel walls as well as the openings.
It was in one of these mazes that I found Rhubarb Jam.
You just never know what you are going to find, so my advice, EXPLORE every nook and cranny of this beautiful country, you will never be disappointed.
