Sear the squash and then reduce the heat to medium.
Let the squash brown for about 5-10 minutes until it caramelizes.
Take some stock and de-glaze the pan, scraping up all the good stuff from the bottom of the pan.
Pour in a bit more stock and throw the whole mess (pan and all) in the oven for 10-15 minutes.
Take it out of the oven, and dump the contents into a food processor, add stock, and blend to desired consistency
Add salt, pepper, some cayenne if you want more heat, and some nutmeg to taste.
Serve in warmed bowls, garnish with parmesan and cilantro.
There's lots of room for play in this one. Change nutmeg to cinnamon, use parsley instead of cilantro, use pine nuts for garnish, or use croutons and gruyere...
It's very, very good, and it's a nice mix of flavors that fits in well with california fusion cuisine.
