With the end of summer comes the time of year when I start to think about the Jewish holidays and all of the baking that lies ahead. Taking my cue from my mother, I begin to bake and freeze desserts that I will need to pull out for entertaining or for taking to people’s homes to which we will inevitably be invited. One such item is my mother’s famous Chocolate Chip Pecan Slice, so simple to make and so perfect to freeze. It lasts for weeks, even months in the freezer and when it is half thawed, we slice it into squares and then place in pretty dainty cups.
