I've just been looking through some of our photos and found this happy memory.
Sarah discovered this Halva outside Dongzhimen Subway Station in Beijing, where dozens of Uighers were selling massive blocks of it from the back of bicycles.
Resembling an oversized breakfast bar, this Halva consisted of cashew nuts, almonds, peanuts, goji berries and dried apricot, held together with a luxurious honey cement.
Although it started of soft, chewy and pliable, the halva set like concrete over the coming days. The fear of losing a tooth, however, was nothing compared to the rich reward. Sarah and I spent several days munching through our own breezeblock.
