Wheat germ oil, an extraction of the germ, is strongly flavored and expensive. The wheat endosperm, which makes up the majority of the kernel, is full of starch, protein, niacin and iron. It's the primary source of many wheat flours. Wheat berries are whole, unprocessed kernels, whereas cracked wheat is the whole berry broken into coarse, medium and fine fragments. It is removed during the milling of white flour but is left intact in whole-wheat varieties.
Wheat germ is sold raw or lightly toasted.
They are fine grained, often with one side slightly coarser than the other. Knives should periodically be honed on whetstones to keep them really sharp. This is done by first lubricating the stone with oil or water, then drawing the knife blade with slight pressure across the whetstone at about a 23-degree angle. Doing this 8 to 10 times on each side of the knife is adequate. If the whetstone's two sides are of differing textures, this activity should be performed first on the coarser side and finished on the finer-grained side.
