I had never eaten butternut squash before so fixed it plain and then went from there, it started by my using orange juice in it. The next time, I just expanded on the idea and added more stuff and found I did not have any OJ but did have mango juice and it came out 'licious!
Peel the squash and cut in chunks, boil in salted water till tender. Drain well and let dry a bit. Preheat oven to 350. Take squash and mash with potato masher, then add the remaining ingredient one at a time and mix well. Spread this into a buttered casserole. Bake for 30 minutes.
You can use orange juice and add a bit of orange zest into it. Then at the end spread a little orange marmalade over the top and broil it just a couple of minutes.
