Heat a wok (kadhai) on high. Once it is hot, switch it to medium and add the whole spices viz. coriander seeds, cinnamom stick, black peppercorns, cloves, whole red pepper, black cardamom etc . and stir them till they are roasted. If you like poppy seeds (khuskhus) , you may add 2 tsp of it here and roast it with the spices. Alternatively, you may roast these spices in clarifid butter too.
