Method
- Sift almond flour and powdered sugar twice to remove lumps.
- Beat egg whites to soft peaks, then gradually add granulated sugar until stiff peaks form.
- Add vanilla and a small amount of purple gel coloring.
- Fold dry ingredients into the meringue using macaronage until batter flows like thick lava.
- Pipe circles onto lined baking sheets and tap trays to release air bubbles.
- Rest shells 30–45 minutes until a skin forms.
- Bake at 300°F (150°C) for 13–15 minutes and cool completely.
- Beat butter until creamy; add powdered sugar, blackberry purée, vanilla, and salt.
- Pipe buttercream onto half the shells and sandwich with remaining shells.
- Mature 24 hours before serving.
Notes
For deeper flavor, use fresh blackberry purée strained of seeds. Mature macarons at least 24 hours for best texture.
