I can't remember exactly, but I think I came across this recipe via the Kitchn blog, which is a fairly recent addition to my Google Reader. I've been an Apartment Therapy reader ever since I moved to LA and needed ideas to decorate and furnish my apartment, but their AT sister blog focused on cooking and kitchens is truly exceptional. Tons of great recipe ideas and clever kitchen design/appliance ideas.
The actual recipe comes from Cooking Weekends, and I was intrigued by this recipe for two reasons: first, of course, I love all things chocolate, and second, it calls for corn starch, which I've never included in shortbread before. I adore the way shortbread cookies simultaneously crumble and melt in your mouth, and corn starch is supposed to enhance that characteristic -- winning on all fronts!
Now, back to those four different kinds of chocolates... I decided to play a taste test game (with myself, eek!), using different chocolate bars to figure out which ones work best in the shortbread. The four bars I used were a Trader Joe's 73% organic cacao, an 85% dark from Divine, at 70% dark chocolate orange from Theo, and 70% Madagascar dark from Rogue Chocolates called Sambirano.
My favorite for eating is the Theo, but it turns out that the best one for these cookies was the $2 TJ's bar! I think the cocoa butter content in that bar is a little higher than the others, so it melted to a wonderful creamy consistency.
Go figure! Sometimes cost isn't everything, even when it comes to chocolate. Without further adieu, here is the recipe, courtesy of Cooking Weekends:INGREDIENTS
1/2 cup cornstarch
1/2 cup icing sugar
1/8 tsp fine sea salt
3/4 cup unbleached flour
1/4 cup whole wheat pastry flour
3/4 cup unsalted butter (1 1/2sticks), cut up
2 tsp vanilla extract
4 oz baking chocolate bar, broken into 16 pieces
DIRECTIONS
Place the cornstarch, icing sugar, salt and flour into the bowl of a food processor and pulse a few times to combine. Add the butter and sprinkle the vanilla extract evenly over the top. Run the motor until a soft dough begins to form.
Preheat oven to 300°F.
Divide the dough into 16 equal pieces. Encase a piece of chocolate inside each piece of dough.
Place the cookies about an inch (or more) apart of an ungreased cookie sheet. Bake for about 25-35 minutes or until the edges begin to brown.
Remove from oven and cool on baking sheet for a minute or two, then remove shortbread onto a wire rack.
