Get-Ahead: Combine all the wet ingredients, and all the dry ingredients, and store separately in the refrigerator overnight. Stir the wet and dry together in the morning while you preheat the griddle. Double Up: I always make two batches of these, but they are most tender when I mix up one batch at a time, start cooking them, then repeat, so I've given you a single batch here. Buckwheat Flour: Chances are your regular grocery store will only carry one kind of buckwheat flour, and whatever kind you get will work, but flours from different brands yield slightly different results. If your buckwheat flour seems coarse, and flecked with dark gray bits, you'll get slightly darker pancakes (it's what I prefer). Buckwheat flour can also be labeled light, which is finer, a subtle gray color, and yields a more delicate pancake. It can also lend an odd greenish hue, but they still taste delicious. My family never complains.
