To make pancakes, in medium-sized bowl, whisk together buckwheat flour, baking powder, salt, and caraway seeds. In small bowl, lightly beat egg and combine with buttermilk, maple syrup, and oil. Make a well in center of dry ingredients and pour in wet ingredients. Whisk together, until just combined. Heat cast iron skillet or grill to medium-high. Drop tablespoons of batter onto hot grill. When bubbles appear on the surface of each pancake, flip and cook the other side (about 30 seconds). Continue until all batter is used.
