The Grill is designed to be preheated before use. Even overcast skies can build into a heated chamber ready to cook. Once heated, medium and large dishes will require at least partial Sun to continue cooking.
How do I know when my food is done?
Many foods will finish cooking when the internal temperature of the food hits near 212°F/100°C. This means that steam is a strong indicator of a dish's progress. Noticing smell is another easy and surprisingly intuitive way to judging your food's progress. Give it a couple tries and you'll be a pro.
