When I was a kid my mother always made pumpkin-cranberry muffins in the Fall so I associate them with changing leaves and cold mornings waiting for the school bus, but these sweet and richly satisfying muffins are good any time of year. A can of pumpkin puree from the store will do just fine for this recipe, but if you’re blessed with an abundance of pumpkins in your pantry like we are, making your own is very simple.
