Rhubarb Ketchup

This Rhubarb  Ketchup is rather savoury compared to the all tomato, store bought kind.

You would not be able to pick out that it is rhubarb…it is just savoury. I loved it on hamburgers.  But it would be good with any grilled meat -chicken, pork chops etc.  Try it in pulled pork!

It takes a while to make but it isn’t hands on time if you are around the kitchen you can just stir it occasionally.

I am not sure how long it would keep in the fridge.  A week would be okay but not sure after that so I froze what I didn’t use in small containers.
