This spice mix can be stored for a week or so. Store them in an air tight container. There are also so many variations to this recipe. We can add a bit of tamarind while grinding. Some add garlic to it. If you are using these, Ill advise you to finish up the spice mix in a couple of days, as it may go rancid quickly.
