Not traveling as I once did has caused me to miss things that were once common for me.
Scandinavians are generally not much into breakfast---a cup of strong coffee and maybe a small pastry is about it. However, in hotels that cater to international guests they all put on a spread for breakfast---and always on the table is fish of various types. Most common are salmon gravlax, smoked salmon, eel and white fish and raw herring in wine sauce and sour cream sauce.
The Dutch are also into raw herring---even to the point of street food vendors in Amsterdam selling whole fishes---often eaten at one go.
So---I was very surprised last week when my wife found a jar of herring in sour cream So this week----I got a jar of herring in wine sauce
....and yes you can be sure tomorrow morning I will have herring with my double strength Sumatra black coffee
That will be a new staple in my refrigerator
...and my friends in Texas---HEB has it
