How to Make Coffee Ganache
Infuse heavy cream with coffee.
Melt the chocolate in the microwave using 30-second intervals.
Add glucose syrup to coffee-infused heavy cream. If you use the cold infusion method, warm heavy cream with glucose syrup.
Pour the warm mixture in thirds over melted white chocolate, stirring after each addition with the help of a rubber spatula.
Emulsify the ganache with an immersion blender until smooth.
Transfer the ganache into a glass container and cover it with plastic wrap “to contact.”
Refrigerate for 5-6 hours or until the ganache develops a creamy consistency.
Transfer the ganache to a piping bag with a round pipping tip and fill macarons.
How to Make Macaron Shells
In the mixing bowl, sift together almond flour, powdered sugar, and espresso powder. Set aside.
In the mixing bowl of a stand mixer add room-temperature egg whites and start whisking on low speed. Start adding sugar one tablespoon at a time. Add food coloring.
Increase speed to medium-high and whip until glossy and medium peaks. This will take 10-15 minutes.
Add dry ingredients into the meringue and start folding the butter. The batter is ready when you can make a figure 8 with a spatula, or it flows “like lava.”
Transfer macaronage into a pastry bag with a round tip.
Pipe macaron shells on the baking mat. Sprinkle macaron shells with espresso powder (optional).
Top the baking sheet pan with pipped macaron shells a few times. Let shells rest on the countertop until no batter sticks to your finger when you touch it.
Bake macaron shells in the preheated oven to 275oF (134oC) -300oF (150oC) for 12-14 minutes. Oven temperature and baking time may vary, depending on your oven.
Remove baked macaron shells from the oven and let it cool on the baking mat with a baking sheet pan. When shells are cooled completely remove them from the baking mat and pair them with similar sizes.
