Potato and Cauliflower Curry (Aloo Gobi)

In traditional recipes for aloo gobi, the vegetables often are fried before being simmered. But we wanted a simpler, neater cooking method as well as a lighter, fresher flavor. So we opted instead to roast the cauliflower and potatoes in a high-heat oven. Before roasting, we tossed the vegetables with a little cornstarch, which assists with browning and crispness, and also helps thicken the curry when the ingredients are later simmered.
