Here's a good, authentic Irish recipe for St. Patrick's Day! It is great served with a hearty beef stew. I got this particular one off food.com.
Irish Soda Bread
4 cups flour
1 1/2 teaspoons salt
1 teaspoon baking soda
2 cups buttermilk
Preheat oven to 375 degrees and grease a baking sheet or round pan.
Mix the flour, salt, and baking soda; add the buttermilk and stir briskly with a fork until the dough holds together in a rough mass.
Knead on a lightly floured board for about 30 seconds, then form into an 8-inch round, about 1 1/2 inches thick.
Slash a large about 1/4 inch deep X across the top, and bake for 45-50 minutes, until browned and the X has spread open.
Cool on a rack, and then wrap in a slightly damp towel and let rest on the rack for at least 8 hours.
