I decided to do a little baking and settled on Irish Soda bread: quick, easy and toastable. Yet leaving my GW digs in two weeks, I didn’t want to stock up on ingredients. Hampered by circumstance and forced to make due, here is what I learned.
Baking powder can be substituted for baking soda; it takes about three times as much baking powder as baking soda to get the same rising effect.
Buttermilk isn’t a common item at college supermarkets….obviously. So I made my own: 1 tbsp lemon juice or white vinegar into one cup milk and let stand for ten minutes. It isn’t as thick, but gets the job done.
That’s all; sweet and to the point, just like the Soda Bread.
