Irish soda bread is a classic, but it only became an Irish staple in the 1840’s. It is a quick bread. It uses baking soda instead of yeast. Sour milk (buttermilk) activates the baking soda. Housewives traditionally cut crosses on the top of the loaves. The addition of raisins and citrus zest is not traditional, but no reason to avoid flavor enhancements.
I used this recipe from the Barefoot Contessa, substituting raisins for currants: http://www.foodnetwork.com/recipes/ina-garten/irish-soda-bread-recipe-1949134
It was great. Give Irish soda bread a second chance.
