I created these squash puffs duchess potatoes style the day after I prepared for the first time my Buttercup squash and blue cheese puree. It has been a great solution to make use of the remaining puree. The result has been so tasty, and often I prepare them as the main recipe, without waiting to have leftovers! This recipe is easy to make, and the puffs are perfect both as an appetizer and as a side dish. A crispy crust with a tender heart!
