In the autumn a variety of squash come on the market as people use them for decorations. Many are quite good to eat and make a beautiful presentation. These are a form of acorn squash which are called, "Calico" besides being as delicious as acorn squash, they are beautiful on the dinner plate.   These are simply prepared as you would an acorn squash. Because it was so large, I cheated a little bit in the preparation. After splitting and cleaning, I placed them cut side down on a china plate and micro waved them for a few minutes until they were softened. This steams the squash in its own liquids and speeds up the oven time a lot. Sprinkle the insides with brown sugar and place some pre cooked bacon in the cavity. About half an hour before serving, put them in a 350º oven to finish them off. It made a good combination with an autumn dinner of roast pork and mashed potatoes and gravy.
