This recipe is over 300 years old! I found it in an old cookbook and cherish it dearly. Bear in mind this is a very dense, very rustic loaf, and creates a very hard crust. But it is fun for an authentic Irish treat. Because of the recipes age, all of the rising comes from the buttermilk, rather than bread soda (baking soda). If you prefer a lighter loaf, you may add 1 t. of bread soda to the dry ingredients.
This is a recipe direct from my Irish/Welsh ancestors. Keep in mind, sugar and other ingredients were hard to come by before the early 1900's.
Here's a thick, heavy soda bread perfect for soaking up the last drops of stew in your bowl or the beer in your stomach!
As far as organ meat goes, heart is probably some of the most tame you can try. When I first had this, I honestly thought it was an elk roast, or perhaps moose. It was that good! Bear in mind that it is a very low-fat cut, so over cooking will dry it out quickly. This is one I have made a few times for a Sunday roast. When I didn't tell people what it was, they assumed it was just a beef or venison roast!
