James here, on a sad day. Here at my desk, I’ve just eaten what’s probably my final serving of smoked herring paste. Danish manufacturers PK Konserver seem to have discontinued making this wonderful concoction. In fact I think they stopped making it months ago but I had stored a few tubes away in the freezer. Now I’m down to none. Thankfully, they still make the smoked cod roe paste. There’s probably someone out there in Scandinavia making the herring paste… if so, please get in touch.
