Here is my brother's recipe, I ended up making this Saturday down at my Mom's, turned out to be a big hit. The Rye Croutons were the perfect topping. Mom made some excellent soda bread which we ate warm out of the oven and slathered in butter.
I added a Guinness or two along side and truly felt the luck of the Irish running through my veins!
