Look for sugar pumpkins and cheese pumpkins—we find they make the tastiest purée for pies, tarts, and cakes.
fresh pumpkin, cut into roughly 4- by 5-inch wedges
unsalted butter, melted
Preheat oven to 400°F.
Brush flesh sides of pumpkin wedges with butter. Arrange, flesh side down, in a large roasting pan and cover pan tightly with foil. Bake, turning pieces after 1 hour, until flesh is very tender when pierced with a fork, about 2 hours. Remove foil and cool pumpkin in pan until it can be handled.
Discard any liquid that may have accumulated and scoop out pumpkin flesh, then purée pulp in batches in a food processor. Transfer to a large sieve or colander lined with several layers of cheesecloth set over a large bowl. Drain purée, chilled, its surface covered with plastic wrap, 8 hours or overnight.
Cooks’ note: Purée keeps, covered and chilled, 2 days or, frozen in an airtight container, 2 months.
