Start by preheating your oven to 375°F. Take your cherries and toss them into a saucepan with a heavy base. Stir the water and cornstarch together until smooth, and then drizzle this mix right over the cherries. Sprinkle in the sugar and let it all cook on medium heat until the cherries thicken up beautifully.

Once your cherry mix is nice and thick, give it a taste and tweak it with some lemon juice, then just cover it up to keep it all warm and cozy. Now, in a separate bowl, whisk together your flour, 1/4 cup sugar, and baking powder. Work the cold butter into this mix until it's nice and crumbly.

Beat the egg and buttermilk together, then quickly fold it into your flour mixture. You want to mix until just combined so it stays lovely and light. Pour the warm cherry sauce into a 2 1/2 quart baking dish. Then, with a fork, drop clumps of dough right on top of the cherry layer. Sprinkle the top with the rest of your sugar.

Pop it in the oven and bake for about 20-25 minutes, or until the topping is perfectly golden and cooked through. This dish is absolutely divine whether served warm or chilled!
