Ark of Taste Project is a special listing of unique foods established by Slow Food, the food advocacy organization. They've catalogued over a 1000 unique foods that are labeled extraordinarily delicious and endangered, including Sibley.
Here's how I enjoyed the fruit this week with a friend for lunch: I halved the squash with a serrated knife, scooped out the seed (and saved it of course...Sibley is open pollinated so the seeds will come up true to type next year) and baked until soft at 350 degrees. I let cool to handle, and then spooned out the flesh into a Cuisinart with some low fat unflavored yogurt and a quarter cup of walnuts. I tossed in a couple cloves of garlic, salt, pepper and a quarter of a jalapeno for heat, and pureed. I reheated just before serving and once in bowls I topped with bread crumbs and shredded parmesan cheese, and used a kitchen torch to toast and melt the cheese at the table.
