This, which I bought today, is 大列巴 (dà liè bā), a bread made in the far north east of China, near the border with Siberia, Russia. It was introduced from Russia to China in the 1950s. It is, as you can maybe see, laced with raisins. 大 (dà) means 'large' and 列巴 (dà liè bā)) is a sad attempt to phonetically render хлеб, the Russian for bread into Chinese. Big bread.
In Russia, it is normally a rye bread but this one is wheat.
The raisins bring sweetneess, but like it with my sharp cheddar.
