Saint Wenceslaus (Vaclav) I, Duke of Bohemia (assassinated c935), subject of the Christmas season carol "Good King Wenceslaus", and patron of the Czech Republic and its capital city of Prague.
As patron of the Czechs, his feast day is also Czech Statehood Day, which has been celebrated since 2000.
As it says on expats.cz, "Czech food is not exactly diet food." No, indeed. It is hearty, flavorful food that won't leave you feeling hungry an hour later.
BEEFSTEAK NA KYSELO
Thinly slice 1-1/2 pounds of round steak. Trim slices and cut into 1-1/2 inch pieces.
Heat 1 tablespoon lard [shortening or butter also work] in a heavy skillet; add meat and brown on both sides. Lower heat; sprinkle meat with 1 teaspoon of salt and top with slices from 1 large onion. Pour 1 cup of boiling water over the meat; cover and simmer for about an hour or until meat is tender. (Check the liquid occasionally. You don't want it to boil away, and there should be about a cup of liquid at the end of cooking time.)
When tender, transfer the meat to a hot dish. Blend 1 cup of sour cream with 2 tablespoons of flour; stir this into the skillet and mix well with the liquid. Season with salt and pepper to taste, and, if you like, stir in 1 tablespoon of tomato ketchup. Heat through and pour sauce over meat.
Serve with boiled noodles or boiled potatoes or with the famous Czech dumplings, which you can find on My Favorite Czech Recipes blog (along with dozens of good recipes and tips for making Czech food)
And to drink? Well, Wenceslaus is also the patron of brewers, so what could be more appropriate than "the world's first golden beer" - Pilsner, of course.
