Do try Crown prince, only note of caution is size, in a normal year, they are pretty big, have a look at my 2006 squash harvest on my blog.
Superb flavour, cut a plug round the stalk, prise it out, scoop out the seeds and string, put the plug back in minus stalk, place plug side down on roasting tray and roast till a carving fork goes in easily.
The inside steams, the upside down is to stop warm water preventing the base from cooking, allows water to get out.
Use what you can with your roast meat & other veg.
scoop out the rest of the cooked flesh, pop it in the fridge and use on a subsequent day as a soup ingredient.
