The other day I stumbled upon my mother's collection of old recipes. I sat for a long time looking at recipe after recipe scribbled on thin pieces of paper or, in fancier cases, stiff recipe cards. One seasonal recipe grabbed my attention: Nabby Apple Cake. Nabby? Oh! I bet the writer meant nubby. The idea of a cake studded with apple pieces sounded good to me. And if my mom kept the recipe, it must be worth making.
