This recipe features a tender, perfectly roasted whole head of cauliflower served with a creamy, flavorful garlic tahini sauce. The cauliflower is first boiled, then steamed, and finally roasted to achieve a golden-brown exterior. The sauce, described as good on any vegetable, combines sautéed minced garlic with lemon juice, tahini, maple syrup, salt, cumin, and ice-cold water for a smooth consistency.
