Yes to the Black Cardamom, you're the 2nd person to spot that.
The one on the far right has been ID'd as mace by haldi, & a Google image search confirms that it does look very similar so Mace it is I reckon!
Their Hyderadad Lamb Korma went something like:
Shed load of thinly sliced onions (Spanish as far as I could tell) frying away in loads of oil (colouration of Sunflower oil) - absolutely swimming in the oil. Then that tray of spices got chucked in & stirred about followed by lamb, literally "slow cooked on the bone" (for I guess about 10 to 20 mins).
Chilli Powder, Turmeric & salt was then added followed by a huge slab of Garlic & Ginger paste. It was then cooked for 1/2 hour before serving.
Viola! Hyderadad Lamb Korma. If you can, watch that episode.... Observations & comments please!
