First, peel the garlic and ginger.
Then heat a frying pan on medium heat.
Roast cumin and coriander seeds in it without fat for a few minutes. When they are golden brown and aromatic, remove the pan from the heat. Finely crush the roasted spices either in a mortar or grind them to a fine powder in a food processor. At the end, process with all other ingredients in a food chopper to a smooth paste.
