Calling all rhubarb lovers and those with an overabundance of this tart gem. This is a new twist on using rhubarb in that it isn't a dessert or a salad, but part of a main course. This recipe hails from the Jewish community of Rhodes and appears on the Seder table in both Greece and Turkey (in Greece, one part rhubarb to two parts tomato; in Turkey, the proportions are reversed). If you don't care for the tartness of rhubarb, this recipe isn't for you. I'd also recommend trying this sauce on chicken and pork as well as fish. Enjoy!
