Crumbly strawberry-rhubarb crumble

I made this a few weeks ago, but between work, Sophie, and a trip to the East Coast (where I had the opportunity to eat here and here in one gluttonous day--no one can say I don't seize the moment!), I had trouble getting it into a post. But it was too good to be forgotten. So, although it's belated, and rhubarb may have vanished from the grocery store, let me tell you about this strawberry-rhubarb crumble. If you can't make it now, you can make it next year. And you can certainly steal the secret to the crumbly topping and use it on any kind of fruit.

I myself nabbed the entire recipe from smitten kitchen who borrowed the idea from the divine Nigella Lawson. What's the great concept? Leavening in the topping. As in: baking powder.

Yeah, I was skeptical too, but believe me when I say, this is worth trying. It results in big crumble-y crumbs--no little pesky tidbits masquerading as topping. It's perfect and delicious. 

Oh, and there might have been some Madagascar vanilla ice cream involved...

Strawberry-Rhubarb Crumble

From smitten kitchen

Yields 6 to 8 servings.

For the topping:
1 1/3 cup flour
1 teaspoon baking powder
3 tablespoons sugar
3 tablespoons Demerara sugar (or turbinado sugar aka Sugar in the Raw)
Zest of one lemon
1/4 pound (1 stick or 4 ounces) unsalted butter, melted

For the filling:
1 1/2 cups rhubarb, chopped into 1-inch pieces
1 quart strawberries plus a few extras, hulled, quartered
Juice of one lemon
1/2 cup sugar
3 to 4 tablespoons cornstarch

Pinch of salt

1. Heat oven to 375°F. Prepare topping: In a mixing bowl, combine flour, baking powder, sugars and lemon zest and add the melted butter. Mix until small and large clumps form. Refrigerate until needed.

2. Prepare filling: Toss rhubarb, strawberries, lemon juice, sugar, cornstarch and a pinch of salt in a 9-inch deep-dish pie plate.

3. Remove topping from refrigerator and cover fruit thickly and evenly with topping. Place pie plate on a (foil-lined, if you really want to think ahead) baking sheet, and bake until crumble topping is golden brown in places and fruit is bubbling beneath, about 40 to 50 minutes.
