By way of variation from the version discussed by Dr. Long above, this is the recipe my Grandmother from Co. Mayo used and which we continue to make -

She would alway grease the pans and never cut a cross. This version also uses both baking soda and baking powder. Given that I grew up eating this type of soda bread, the Carroway Seed is an essential part of the taste to me. Note that is a double recipe.

The Odlum's flour and mixes of the type Dr. Long was holding up are available on Amazon, but are quite expensive.
