Help with substitutions for Passover

Diane in Bexley | Mar 5, 201209:39 AM

I saw this recipe on the Smitten Kitchen website for blueberry crumble bars and want to make them for Passover. I am posting the original recipe. Please help me figure out how to substitute matzo meal (matzo cake meal?) and potato starch for the white flour and cornstarch called for in the recipe. Is it an even substitution? more? less? Any suggestions would be welcome.They are for a dairy lunch, so the butter is OK. Thanks!

1 cup white sugar
1 teaspoon baking powder
3 cups all-purpose flour
1 cup cold unsalted butter (2 sticks or 8 ounces)
1 egg
1/4 teaspoon salt
Zest and juice of one lemon
4 cups fresh blueberries
1/2 cup white sugar
4 teaspoons cornstarch

1. Preheat the oven to 375 degrees F (190 degrees C). Grease a 9×13 inch pan.

2. In a medium bowl, stir together 1 cup sugar, 3 cups flour, and baking powder. Mix in salt and lemon zest. Use a fork or pastry cutter to blend in the butter and egg. Dough will be crumbly. Pat half of dough into the prepared pan.

3. In another bowl, stir together the sugar, cornstarch and lemon juice. Gently mix in the blueberries. Sprinkle the blueberry mixture evenly over the crust. Crumble remaining dough over the berry layer.

4. Bake in preheated oven for 45 minutes, or until top is slightly brown.
