Serves 8-10
1 lb. rhubarb
1 lb. strawberries
1 tablespoon cornstarch
¾ cup sugar
zest of one lime
pinch of kosher salt
2 cups flour
2 teaspoons baking powder
½ teaspoon kosher salt
1/3 cup sugar
½ cup (1 stick) butter, cold
½ teaspoon vanilla
1 cup buttermilk
2 teaspoons milk
2 teaspoons demera sugar
Preheat the oven to 375ºF. Wash rhubarb and cut into 1-inch lengths. (This should yield about 3½ cups.) Wash strawberries, cut off stem and slice in half. (This should yield about 3 cups.) Place rhubarb, strawberries, cornstarch, sugar, lime zest and salt in a large bowl and stir to combine. Set aside.
Transfer fruit to a 12 x 8½-inch (2 quart) baking dish. Break off portions of the dough (about 8-10) and arrange over the fruit. Brush the dough with the milk and sprinkle the sugar over both the fruit and dough portions of the dish.
Place in the oven for 50-55 minutes, until topping is golden brown and juices are bubbling.
Let cool on rack 30 minutes before serving. Serve with vanilla ice cream.
