Step 1: Prepare the Macaron Shells Sift the powdered sugar and almond flour together to get rid of lumps, then whisk the egg whites and granulated sugar over simmering water until they’re frothy and the sugar dissolves. Transfer this mixture to a mixer and whisk on high speed until you reach stiff peaks aim for a glossy texture with clear whisk streaks, but don’t overdo it. Gently fold in the sifted dry ingredients using a J-motion, adding a drop of purple food coloring if you want that extra pop of color, until the batter is thick, glossy, and flows like a slow ribbon forming a figure 8.

Step 1: Pipe the batter into 1.5-inch circles on parchment-lined baking sheets, then tap the trays firmly to release any air bubbles. Let the shells dry uncovered for 20-40 minutes until the surface feels dry to the touch. Preheat your oven to 300°F (150°C) and bake one tray at a time for 16-20 minutes, rotating after 6 minutes for even cooking. Once done, cool them completely before moving on.

Step 2: Make the Blueberry Jam Combine the blueberries and maple syrup in a saucepan, cooking over medium heat while stirring until it reaches a gentle boil, then simmer for 5 minutes. Mix the cornstarch with water and add it to the blueberries, bringing it back to a boil until it thickens nicely. Strain through a fine-mesh sieve, pressing to get all that liquid out, and chill it completely in the refrigerator. This jam not only stars in your macarons but can also jazz up your breakfast routine, like on toast or oatmeal it’s that versatile, as mentioned in the notes.

Step 3: Prepare the Mascarpone Filling In a mixer, gently beat the mascarpone cheese and powdered sugar until they’re just combined don’t overmix to keep it creamy. Add the vanilla extract, then in a separate bowl, whip the cream until stiff peaks form. Fold the whipped cream into the mascarpone mixture gently, and for a fun twist, mix in 2 tablespoons of the cooled blueberry jam to create a bicolor effect. This filling brings a smooth, luxurious touch to your macarons, making each sandwich a delight.

Step 4: Assemble and Store Pipe the filling onto the flat side of one cooled macaron shell and sandwich it with another shell. Refrigerate the assembled macarons overnight to let the flavors meld for the best taste and texture. As a tip, these keep well in the fridge for 4-5 days or frozen for up to 2 months, which is perfect for meal prep.
