I like to make mashed sweet potatoes or acorn squash, replacing the milk or cream with orange juice.
Somewhere on another thread I have posted a wonderful recipe for an apple cake that is very simple, fairly healthy and delicious. When I have more time, I can repost it here if some one would like it.
This is also the time of year to make pumpkin and sweet potato breads--which are delish with cranberries, walnuts or pecans added. They freeze well also, and make nice Christmas gifts. I can post a couple of recipes, but they are readily available in good cookbooks.
