adapted from Better Homes and Gardens

makes 4-6 servings

Ingredients
3 lbs butternut squash, peeled, seeded, and cut into chunks
2 Tbsp butter
1/3 cup sour cream (or 1/2 cup mascarpone cheese. I REALLY want to try this but didn't have it on hand)
1/4 cup maple syrup
2 tsp finely shredded orange peel, plus some reserved for garnish (from 1 medium orange)
2 tsp finely shredded lemon peel, plus some reserved for garnish (from 2 small lemons)
3/4 tsp salt
1/3 tsp ground black pepper
2 Tbsp snipped fresh sage
1/2 cup pecans, toasted and coarsely chopped
      sliced green onion and/or fresh sage leaves

1. In large pot cook squash in lightly salted boiling water, covered, 16-17 minutes or until tender. Drain.
2. Meanwhile, melt butter in small skillet over medium heat, whisking constantly until golden brown, 3-5 minutes. Transfer half the squash into blender or food processor. Add butter, sour cream, maple syrup, orange and lemon peels, salt, and pepper. Cover and process until smooth. Place remaining squash in a bowl; add pureed mixture. Mash slightly. Stir in fresh sage.
3. Top with pecans, green onion and/or sage leaves, and citrus peel.
