Seekh Kebabs

These were pretty tasty, if a bit dry.

• I had only 350g of ground beef (rather than 400g) and made only eight kebabs (rather than twelve). Even with the full amount, twelve would have been more like smallish meatballs.
• I didn't add nearly enough salt, so we had to salt them at the table.
• The meat mixture wasn't firm enough to stay put even on my flat skewers. I ended up turning them by hand and using some wooden skewers to hold three or two together in the right position. I think it would be better to start with a pair of wooden skewers in each kebab.
