The stars were aligned. Whole Foods had freshly ground lamb, I had mint, left over from the biyani, walnuts and the lustrous leftover raita (which, in another country, is tztaziki which you have to eat with kefte) and so I whipped a batch up.
They were good (and oh that tzatziki) but I may be getting over my North African spice thing. It all begins to taste like chili. Chili with caraway.
