For best flavor, use very ripe bananas with plenty of brown spots, as they add natural sweetness and moisture to the bread; do not overmix once the dry ingredients are added or the loaf can become dense and tough. Lightly toasting the black walnuts in a dry skillet or low oven before adding them enhances their distinctive, earthy flavor and helps them stay crunchy. If the top begins browning too quickly during baking, loosely tent the loaf with aluminum foil for the last 15 to 20 minutes. This bread keeps well tightly wrapped at room temperature for up to 3 days, and the flavor actually improves by the next day; it also freezes well, either whole or sliced with parchment between slices for easy thawing.
