Milk Street transforms vegetables for the holidays. First, we make Buttery Hazelnut and Winter Squash Tian, shingling thinly sliced pieces of butternut squash for an impressive presentation. Then, we call on cornstarch to make Crisp Oven-Fried Cauliflower with Tahini-Yogurt Sauce and use the "braise and glaze" technique for Moroccan-Spiced Glazed Carrots flavored with garlic, honey and cumin.
