In brief

I'm taking serious advantage of my elective time. For instance, on Thursday I made two flavors of macarons: jasmine with a grapefruit filling, and "margarita" macarons consisting of lime shells with a spicy tequila buttercream.



The lime shells are kind of flat because I overbeat the second batch of batter. The flavor is spot-on, though!

Below are the recipes for each. Note that if you're using colored gels or powders, whip them together with the egg whites and sugar.

Jasmine macarons
contents of 2 jasmine teabags (usually a jasmine and green tea blend)
110 g almond meal (or ground blanched almonds)
200 g confectioner's sugar
90 g egg whites, left out at room temperature for at least 1 hour
30 g sugar
pinch salt

Pulse the almond meal, confectioner's sugar, and tea in a food processor or blender just until finely powdered. Set aside.

In a standing mixer with a whisk attachment, whip the egg whites, salt, and granulated sugar until stiff peaks form but the egg whites are not curdled or dry. Sift the almond mixture over the egg whites, discarding any bits that don't make it through the sifter. Working briskly with a rubber spatula, fold the two together just until a thick, ropy batter is formed. Using a pastry bag or icing plunger, pipe one-inch circles of batter onto cookie sheets lined with parchment paper. The circles should be 1.5 to 2 inches apart to allow good air circulation. Firmly rap the baking sheet on the counter 3 or 4 times to release any air bubbles in the macarons. Sprinkle a little more tea on top of the cookies. Let rest for about 30 minutes, or until a dry crust forms on top.

Bake in a 300-degree oven for 15 minutes. Check halfway through baking; if the macarons begin to brown, turn down the heat a bit. Cool the cookies completely on a rack before filling.

Grapefruit curd
1 tbsp plus 2 tsp grapefruit zest
120 mL (about 4 oz) fresh grapefruit juice
3 egg yolks
115 g sugar
3 tbsp butter
1/8 tsp sea salt
1/2 tbsp cornstarch

Whisk together the cornstarch, sugar, and salt in a small pot. Slowly whisk in the egg yolks, grapefruit juice, and 1 tbsp zest. Heat with the butter over medium-low, whisking constantly, until the mixture is thick. It should take about 10 minutes. Do not let it boil, or the egg yolks will curdle! Strain the mixture into a small container and fold in the reserved 2 tsp zest. Cover with plastic wrap, pressing over the surface of the hot curd to prevent skin formation. Cool to room temperature, then refrigerate.

Lime macarons
zest of 3 limes
110 g almond meal
200 g confectioner's sugar
90 g egg whites, left out at room temperature for at least 1 hour
30 g sugar
pinch salt

Zest the limes, reserving a bit if you'd like to sprinkle some atop the macarons. Pulse the almond meal, confectioner's sugar, and zest in a food processor or blender just until finely powdered. Set aside for at least 20 minutes to allow the lime flavor to permeate the mixture, since the zest will get sifted out.

In a standing mixer with a whisk attachment, whip the egg whites, salt, and granulated sugar until stiff peaks form but the egg whites are not curdled or dry. Sift the almond mixture over the egg whites, discarding any bits that don't make it through the sifter (including the zest). Working briskly with a rubber spatula, fold the two together just until a thick, ropy batter is formed. Using a pastry bag or icing plunger, pipe one-inch circles of batter onto cookie sheets lined with parchment paper. The circles should be 1.5 to 2 inches apart to allow good air circulation. Firmly rap the baking sheet on the counter 3 or 4 times to release any air bubbles in the macarons. Sprinkle some crushed sea salt and, optionally, zest on top; this really needs the hit of salt to work, so don't omit that! Let rest for about 30 minutes, or until a dry crust forms on top.

Bake in a 300-degree oven for 15 minutes. Check halfway through baking; if the macarons begin to brown, turn down the heat a bit. Cool the cookies completely on a rack before filling.

Jalapeno tequila buttercream
1 stick butter
3 egg yolks
1/3 cup sugar
3 tablespoons tequila
pinch salt
2 small jalapenos (deseed if you want, or deseed and add some cayenne later to titrate the heat more precisely), finely minced
optional: 1/4 tsp cayenne
optional: food coloring of some sort

Cut the butter into chunks. You will want it room temperature, but not totally soft, when it's time to assemble the buttercream; let it sit out accordingly.

Whip the egg yolks and salt in a stand mixer until thick and pale. In a small saucepan, mix the sugar, tequila, and jalapeno. Boil until it reaches the soft ball stage, then remove from heat. With the stand mixer on a low setting, slowly and gently pour the hot syrup down the inside of the bowl. When all the syrup is in, turn the stand mixer to high and beat until the mixture reaches room temperature. At that point, start adding your butter about 1 tablespoon at a time, mixing well between each addition. When the butter is completely incorporated, whip on medium-high speed until the buttercream is thick and silky.

Protip: if it breaks/curdles, microwave a small amount until it's melted, but not hot or boiled. Whip this into the remainder of the buttercream at high speed to reconstitute the frosting.
