"Early in the summer, I found an unknown plant growing in my front garden. Think it might be a squash vine, I let it grow and discovered cushaws! Sweet like pumpkins but very green, they make perfect, delectable pies."
Place a steamer insert into a saucepan and fill with water to just below the bottom of the steamer. Bring water to a boil. Add squash, cover, and steam until very tender, 15 to 20 minutes.
Blend squash in a blender until smooth. Pour 6 cups squash puree into a large mixing bowl. Reserve any extra squash puree for a separate use.
Stir cream, honey, eggs, molasses, cinnamon, ginger, 1 teaspoon salt, allspice, and nutmeg into 6 cups squash puree; whisk until smooth. Cover and set aside.
Mix flour and 1 teaspoon salt together in a bowl. Cut butter into flour mixture; add water and mix well. Add more flour to dough if it is too wet. Cut dough in half and roll onto a floured work surface; form into two 10-inch circles. Press dough into 2 pie pans and pour squash filling into each.
Bake in the preheated oven until a knife inserted in the center comes out clean, 40 to 50 minutes. Cool slightly before serving.
