The cobbler as written is pretty tart; if you prefer a sweeter cobbler you may want to take up the sugar a notch, perhaps another 1/4 to 1/2 cup.
- 4 1/2 cups rhubarb stalks (about 1 1/4 pounds or 560 g) cut into 1-inch pieces (Trim outside stringy layer of large rhubarb stalks; make sure to trim away any and discard of the leaves which are poisonous; trim ends.)
- 1 1/2 cups strawberries (1/2 pound or 225 g), stemmed and sliced
- 1/2 cup (100 g) white sugar (1/4 cup to 1/2 cup more if you want the cobbler filling sweeter)
- 2 Tablespoons of quick cooking tapioca
- 1 teaspoon of grated orange peel
- 1 cup (130 g) all purpose flour
- 2 Tbsp white granulated sugar
- 1 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/4 cup (4 Tbsp, 57 g) butter, cut into cubes
- 1/4 cup (60 ml) milk
- 1 egg, lightly beaten
1 Toss the rhubarb and strawberries with sugar, tapioca, zest, let rest: In a bowl, mix the rhubarb and the strawberries with the sugar, tapioca, and orange zest.
Let sit to macerate for 30 minutes to an hour.
2 Preheat oven to 350°F (175°C).
3 Make the biscuit topping: In a medium bowl, whisk together the flour, 2 Tbsp sugar, the baking powder and salt.
Use your (clean) hands to work the butter into the flour until the mixture resembles coarse crumbs, with pieces of butter no bigger than a pea.
Stir in the milk and egg until just moistened (do not over-mix!).
4 Put fruit in casserole, top with biscuit dough: Pour the strawberry rhubarb mixture into a 2-quart casserole dish. Drop the biscuit dough on top of the fruit, like cobblestones.
5 Bake: Bake in a 350°F (175°C) oven for 35 minutes until cobbler crust is golden brown.
Serve with whipped cream (optional).
