Simply Filling/Core - is pickled herring core?

thanks, just the plain stuff, no sour cream or anything?

I think some versions have sugar added, but it might not be a very signficant amount.

I would think it is core? Check the ingredients. I occasionally enjoy marinated herring even tho I know there is some sugar in the liquid.

you know I love the stuff. I never thought about adding it to my core menu, but I saw it in the market today and just wanted some. Thanks
