A brief history of ratatouille

Ingredient insights for perfect roasting

• Eggplant: I love its creamy texture, but it can soak up oil. Salt and drain first, then pat dry.
• Zucchini: Its mild flavor and tender bite make it versatile. Use yellow squash as a colorful alternative.
• Bell Peppers: Sweet and smoky when roasted well. Use red or orange for extra vibrancy.
• Tomatoes: Juicy and brightens the dish. Use cherry tomatoes for a burst of sweetness.
• Herbs: Fresh basil adds a fragrant finish. Dried thyme works well if fresh isn’t available.
