Preheat the oven to 350ºF (177ºC). Grease a 9-inch round pan or cast-iron skillet with butter and set aside. In a large mixing bowl, add flour, sugar, baking soda, baking powder and salt. Toss mixture with hands - this makes it light and airy. 4 cups all-purpose flour, ½ cup granulated sugar, ¼ teaspoon baking soda, 2 teaspoons baking powder, ½ teaspoon kosher salt
Add softened butter to the flour mixture, still using hands, and blend until evenly distributed. Mixture will resemble coarse sand with some large clumps.
½ cup Kerrygold butter
Add raisins and caraway seeds, if using, and toss with hands.
1 cup raisins, 1 teaspoon caraway seeds
In a separate bowl or large measuring cup, beat the eggs with a fork.
2 large eggs
Add the buttermilk to the eggs and blend well.
1 ½ cups buttermilk
Pour the egg/buttermilk mixture into the dry flour mixture a little at a time. Blend well with a just until no dry spots remain. Do not over mix.
At this point, the dough should be heavy but not soupy or overly wet. If it is, add a little flour, 1 tablespoon at a time. If it’s too dry, add a little buttermilk, 1 tablespoon at a time until dough comes together.
Dump dough onto a clean, floured work surface such as a countertop or large cutting board.
Dust your hands with flour and mold the dough into a round - doesn’t have to be perfect.
Place dough into prepared pan and dust top lightly with flour.
Using the wrong end of a fork, cut a deep cross into the top of the dough. This will prevent the bread from cracking while it bakes and gives it the traditional Irish Soda Bread look.
Bake for 50 - 60 minutes or until golden brown. Place the pan on a wire rack to cool. Slice and serve warm with butter or marmalade.
