Step 1 of 4

Heat the oven and dress the vegetables

Heat the oven to 425°F. Toss the cauliflower florets and potato chunks in a large roasting tray with the oil, cumin seeds, turmeric, ground coriander, ginger, chillies and salt.

— Use the biggest tray you own. Vegetables in a crowded tray steam, and a steamed aloo gobi is a wet one.
