<human>:  What's the difference between a roast and a bake?
<bot>: The main difference between a roast and a bake is the temperature used. A roast typically uses high temperatures to cook the food quickly, while a bake generally uses lower temperatures to produce a more evenly cooked meal. Roasting is often used when cooking meats and vegetables, while baking is commonly used for desserts, breads, and other pastries.
