as you know we make all our own powders etc ( because they ain't available ) - it goes in our garam masala and our balti masala and yes Colin a pinch in black tea is smashing - but don't over do it in the tea
And if you make iced tea like me, green tea with lemon grass a smidgen of cardamom in fantastic on a hot day! ie everyday here...
The reason for asking about the cardamom its a bugger to grind all the shell away without having some tiny stringy bits left in the finished powder.
