6. Cooking Guidelines
For best results, always refer to specific recipes or cooking charts. General tips include:
- Preheating: Preheating is recommended for most recipes to achieve optimal crispiness and even cooking.
- Shaking/Tossing: For even browning and crisping, shake or toss ingredients in the baskets halfway through the cooking time.
