I've found another great blog--semiswede! The author is Maia Brindley Nilsson, a fairly recent (2008) American immigrant to Sweden, where she is a "featured monthly writer for The Local, the Swedish news in English."
Swedish food was the stuff of my Catholic childhood lived in exile among mostly Scandinavian Lutherans--many of whom had cooks!! Imagine my delight when I spotted this headline among Nilsson's recent articles: "Ten soul-satisfying Swedish comfort foods"!!! And on the list? One of my all-time favorites--yellow pea soup!! Here's what Nilsson says:
"Ärtsoppa or yellow pea soup has been a Thursday tradition in Sweden since the Middle Ages when Sweden was largely Catholic and Friday was a day of fasting. Filling up on the hearty pork-filled soup was intended to get you through the next day’s fast.
Today the tradition is still going strong as evidenced by the profusion of plastic-cased tubes of pea soup in supermarkets year-round. If you really want to warm up you can chase it with a little warm punsch which became a popular addition to the pea soup tradition during the 1800s."
(You used to be able to get canned yellow pea soup wherever Habitant soup was sold. In the US, that would be close to the Canadian border, as Habitant was made in Montreal (I think--the label was partly in French, I remember that).
