something like schnapps

The something is akvavit, a strong clear spirit similar to acqua vitae, eau-de-vie [cognate terms] and, as you note, schnapps. It is served very cold, right out of the freezer, in small glasses. You toss it back and chase it down with a beer. I ate a lunch similar to a smorgasbord years ago with the officers of a Norwegian freighter. We started with a lavish spread of smoked and pickled fish, most of which, as Dr.Bill notes, are unobtainable in the U.S., all delicious. This was followed up by filet mignon from Buenos Aires and homemade French Fries, accompanied by the akvavit/beer routine. One of the most fabulous meals I have ever eaten. I have no idea how I got down the gangway or how I got home.
