DB October 09- Parisian Macarons

The 2009 October Daring Bakers’ challenge was brought to us by Ami S. She chose macarons from Claudia Fleming’s The Last Course: The Desserts of Gramercy Tavern as the challenge recipe. Unfortunately, it seems nearly everyone found this recipe to be quite problematic, and as a result the recipe I'll be posting will not be the challenge recipe.
I didn't really succeed the way I would have liked to, but at least a few came out looking kinda okay. They're pretty flat, but they have feet, not tutus, and are mostly round. My batter ended up runnier than I had thought and the first tray ran all together to make one big blob (still with feet, YAY! feet!!). The second tray had far fewer macarons piped onto it, but due to uneven heat in the oven (and despite a stack of half-sheet-pans) they rose a bit unevenly and some are much taller on one side than the other.
The recipe I used comes from Helen of Tartelette ( http://www.mytartelette.com )

Basic French Meringue Macarons
100g weighed egg whites- I used the whites in a carton from Trader Joe's- room temperature
2 tsp of powdered egg whites- I used Wilton Meringue Powder
50 g sugar
200 g powdered sugar
110 g Almond meal- this also came from Trader Joe's and wasn't blanched, but I like the speckle-y look
Paste food color- I used orange gel color by Wilton

1. In a clean bowl with clean beaters whip the egg whites and meringue powder to a foam, then gradually add the sugar. Whip until stiff peaks form
2. In a food processor, grind together the almond meal and paste color. I added the powdered sugar after the color and almond meal were evenly combined to aerate and eliminate lumps.
3. Pour the almond meal and sugar onto the meringue and quickly mix, using as few strokes as needed. It should look glossy and be pipeable.
4. Fill a pastry bag or zipper bag fitted with a half inch round tip with the batter and pipe small rounds onto parchment paper on upside-down baking sheets. Bang the pan of shells down onto the countertop to release bubbles.
5. Preheat the oven to 300 degrees F (150C). Let the macarons sit out for an hour and bake for 10-12 minutes. Let them cool before removing from the parchment. Let cool completely before filling.
6. Pipe filling onto half the shells and top with remaining shells.
