Transfer the washed buckwheat into a medium-sized pot with a lid. Add 2 cups of water, 1 tablespoon of extra virgin olive oil, 0.5 teaspoon of salt, and 0.25 teaspoon of freshly ground black pepper if desired. Leave it to boil over medium heat without closing the lid yet. When the water begins to boil, reduce the heat to the lowest setting, close the lid of the pot tightly, and let it cook for approximately
15-20 minutes until the buckwheat absorbs all the water. Be careful not to open the lid or stir during the cooking time; this ensures the steam stays inside the pot and the grains swell evenly, otherwise, you may cause the buckwheat to become mushy.
