Preheat the oven to 450°F.
In a bowl, combine the okra, cayenne, garam masala, coriander powder and chickpea flour. Season with salt and mix well.
Spread the okra mixture in a baking tray and roast till richly browned. The original recipe said 15-20 minutes but it took me a good 40 minutes to achieve this. So check every now and then and remove when the okra has browned well.
Cool to room temperature and store in an airtight container till serving time.
Just before serving, place the beaten yoghurt in a bowl, add the okra crisps, crushed cumin and season with salt.
Garnish with chopped coriander leaves
