Buckwheat groats de John Spottiswood

These are buckwheat kernels that are stripped of their inedible outer coating and then crushed into smaller pieces. Unprocessed white groats are slightly bitter, so before you cook them it's a good idea to toast them in oil for several minutes until they're rust-colored. This removes the bitterness and brings out a pleasant, nutty flavor. If you don't want to do this yourself, you can buy already roasted groats, called kasha.
