Squash Yeast Rolls

2 packages active dry yeast, 1/2 cup lukewarm water (110° to 115°) 1/2 cup puréed fresh Butternut squash (another variety winter squash may be substituted). 1/2 cup softened butter, plus 2 tablespoons melted 1 cup lukewarm milk (110° to 115°) 1 teaspoon salt 1/2 cup sugar 5 to 6 cups flour

Steam the squash and puree in your Cuisinart food processor. Let cool to warm. Pour the lukewarm water into a small warm bowl. Add the yeast and a pinch of sugar. Let it rest for a few minutes, then mix well. Set in a warm, draft-free place for about 10 minutes, or until the yeast bubbles up and the mixture almost doubles in volume. Combine 5 cups of flour, the remaining sugar and salt, sift together into a large mixing bowl. Make a well in the center and pour in the yeast mixture, the squash puree, the milk and 1/2 cup of softened butter. Gradually beat the dry ingredients into the liquid ones. Continue to beat until the dough is smooth and can be gathered into a compact ball. Place the ball on a lightly-floured surface and knead, incorporating up to 1 cup more flour until the dough is no longer moist and sticky. Then continue to knead for about 10 minutes, or until the dough is smooth, shiny and elastic. With a pastry brush, spread 2 teaspoons of the softened butter evenly over the inside of a large bowl. Set the dough in the bowl and turning about to butter the entire surface of the dough. Drape the bowl with a kitchen towel and put it in the draft-free place for about 1 hour to allow the dough to double in volume. Brush the remaining softened butter over the bottom and sides of two 9-inch cake pans. Punch the dough down with a single blow of your fist and, on a lightly floured surface, roll it out into a rough rectangle about 1 inch thick. With a cookie cutter, cut the dough into 2 1/2" rounds. Fold in half and pinch small edges underneath. Arrange about 1/2-inch apart in the buttered cake pans and brush the tops with the melted butter. Set the rolls in the draft-free place to rise for about 15 minutes. Meanwhile preheat the oven to 450°. Bake the rolls in the middle of the oven for 12 to 15 minutes, or until golden brown. Serve the rolls hot. Makes about two dozen
