If you're lucky enough to live near a metropolitan area, then you might have a Russian market. I'd recommend going to one and getting one of the small packages of herring. There usually have whole fillets preserved in what amounts to vegetable/sunflower oil and salt. No sugar added. The flavor of this herring is more pure, and reminds me more of what it's like to get it fresh from a vendor in Holland. It might just be the diabetic predisposition I have due to family members having it, but the idea of herring preserved with sugar like you see with jarred variety, is of off-putting to me.
