01 - Line two baking sheets with parchment paper or silicone mats. Fit a pastry bag with a 0.5-inch round tip.
02 - Sift almond flour and powdered sugar together into a bowl. Set aside.
03 - In a clean, dry bowl, whisk egg whites and cream of tartar until soft peaks form. Gradually add granulated sugar, continuing to whisk until stiff, glossy peaks form.
04 - Gently fold almond flour mixture into meringue in three additions. Optionally tint one-third of batter with yellow coloring for yolk effect. Mix only until batter flows in thick ribbons when lifted.
05 - Transfer batter to prepared pastry bag. Pipe 32 rounds (1.5 inches diameter) onto baking sheets. Firmly tap trays to release air bubbles. Let shells rest 30-60 minutes until surfaces feel completely dry.
06 - Preheat oven to 300°F. Bake 13-15 minutes, rotating trays halfway through. Shells are done when they lift easily from the mat. Cool completely before filling.
07 - Heat cream until simmering, then pour over chopped milk chocolate. Let stand 2 minutes, then stir until smooth. Add golden syrup and butter, mixing until glossy. Tint one-quarter yellow for yolks. Refrigerate until thickened.
08 - Pipe a ring of chocolate filling onto one shell. Place a small dollop of yellow filling in center to mimic egg yolk. Gently press another shell on top. Repeat with remaining components.
09 - Store assembled macarons in an airtight container overnight. This resting period allows flavors to develop and texture to soften properly.
