This time around I attempted the delicate and temperamental macaron. For those of you who don't know what a macaron is, it's like two light wafers sandwiched together with delicious buttercream frosting.
I would not suggest attempting to make these unless you have an entire evening set aside. Even if everything goes the way it should it takes a considerable amount of time to complete these tiny little creations.
First, we'll start with the wafers.
2/3 cup almond meal or ground almonds
1 1/2 cups powdered sugar
3 large egg whites at room temperature and preferably aged up to 3 days
5 tablespoons granulated sugar
1 teaspoon vanilla extract
Preheat the oven to 280º and position two racks in the lower section of the oven. Line two rimmed baking sheets with parchment paper. If you have time, draw 1-inch circles on the back of each sheet, spacing the circles at least 1/2-inch apart. (I did not do this but if you are an anal baker it could make things easier.)
If your almond meal is very coarse, grind it with the powdered sugar in a food processor until fine. (You can also use a blender. I would not suggest using elbow grease and trying to smash them yourself.) Sift the almond meal-powdered sugar mixture twice through a mesh sieve.
Place egg whites in the bowl of a stand mixer (or use a hand mixer) and begin to beat on medium-high. When the eggs are frothy, gradually add granulated sugar one tablespoon at a time until fully incorporated. Continue to beat the egg white mixture until glossy and stiff peaks form when you lift the beaters. (Be patient! It will take a few minutes.) Gently stir in the vanilla extract. Be careful to not overbeat the meringue (e.g., the meringue takes on a clumpy texture).
Add half of the sifted almond mixture and gently fold it into the meringue using a flexible spatula. Lift from the bottom, up around the sides, and toward the middle, being careful to not over-agitate the meringue and lose too much air. Once the almond mixture is mostly incorporated, add the second half and repeat the folding motion.
When the almond mixture is just incorporated, you will need to transform the batter into the appropriate texture. Using the flat of the spatula, "punch" down into the center of the batter, then scrape more batter from the sides to the center, and punch again. (This is when you can add food coloring if you wish!) You will need to repeat this 10-15 times (or more, depending on your arm strength and the beginning texture of your batter) until the batter slowly and continuously drips back into the bowl when you scoop it up with the spatula. Think of the consistency of molten lava. For the best results, check the consistency frequently! Do not make the batter too runny or the macarons won't rise like they should, and you could end up with oil stains on the tops.
Pour batter into a pastry bag fitted with a 0.4-inch tip. You can also use a gallon size Ziploc bag: just snip a teeny bit from one of the bottom corners. Twist and make sure to tightly seal the top of the bag to avoid overflow. On your prepared baking sheets, pipe out 1-inch rounds in the circles you drew. (I just held the bag in the middle and let the batter billow out around it!)
Holding the baking sheet in both hands, rap each baking sheet firmly on the counter two or three times. This smooths out the tops and helps form the frilly foot on the bottoms of the macarons. Allow the piped macarons to dry, uncovered. The macarons should form a very thin, smooth crust where, if you tap it lightly with your finger, the batter will not stick to your finger. If the batter is still sticky, let it dry longer. This may take up to an hour on humid days. (I found it only took a few minutes)
Place baking sheets in the oven (I did one at a time) and bake for 15-18 minutes. After the first 2 minutes, open the oven to allow any excess humidity to escape. Halfway through, swap oven racks and rotate the sheets for even baking. The macarons are done when they are baked all the way through and the shells are just hard. Take care to not underbake (insides will still be mushy) or over-bake (tops will begin to brown). Remove them from the oven, and cool on baking sheet placed on a wire rack.
When fully cooled, assemble the macarons with your choice of filling. The macarons can be stored in an airtight container in the refrigerator for up to one week.
Now on to the frosting! I used a buttercream frosting and boy was it delicious!
7 tablespoons unsalted butter, softened
2 egg yolks
1/4 cup granulated sugar
3 1/2 tablespoons milk
1 teaspoon vanilla extract
Cut butter into pieces and mash with a spatula until the consistency resembles mayonnaise.
In a small bowl, whisk the egg yolks, then add the granulated sugar and whisk until the mixture lightens to an off-white and you can no longer see the granules of sugar. Add the milk, and whisk to combine.
Pour the egg mixture into a small saucepan and heat over low heat, whisking frequently to ensure that the mixture does not curdle or scorch. Cook until the mixture becomes thick and custardy, like pudding. (could take awhile!)
Pour the egg mixture back into its bowl and whisk constantly until it returns to room temperature. Whisk in the butter in three batches, add the vanilla, and stir until smooth and all ingredients are fully combined. (Add food coloring to increase cuteness!) Pipe or spread onto one macaron half and sandwich between the other. (Piping results in a prettier product!)
