Not counting the recipes in all my cookbooks, I have at least 25 different recipes for soda bread that I have made over the last 50 years, from my mom, my grandmother from Cty Fermanagh and many many friends.
I just made 2 loaves, in separate batches. Cooked both in a cast iron skillet and used powered buttermilk for both. Most of the recipes I use are very similar, just slightly different amounts of the same ingredients. None of the better recipes use eggs.
This is good,a lighter cake type bread, not the heavy dense recipe I like. But this was very easy and quick to make.
