Hi Elmore, it's a perfectly valid question though I'm not sure if you are referring to cooking in curries or in rice dishes?
Cardamom can be left in whole
Cardamom can be used bashed as you mentioned
Some recipes (particularly in curries) expect you to cut open the green cardamom and take out the little blacks seeds which are then put in as they are or are grinded.
Brown cardamoms are less commonly used in BIR cooking but when I have used them I've put them in whole and the same for Star Anise. I've not had any problems.
Hope this helps
Steve
