Almond Flour Macarons

Why This Almond Flour Macarons Works

During mixing, the egg whites do most of the work. Whisking them with sugar traps a lot of tiny air bubbles and makes a thick, glossy foam. That foam is what gives the macarons their lift. The granulated sugar keeps the foam strong so it does not collapse right away, and the pinch of salt helps the whites whip up a little faster and more stable.

When the almond flour and powdered sugar are folded in, they coat and surround those air bubbles. The batter loosens and flows, but the air stays trapped inside. Tapping the tray lets big air pockets rise and pop so the shells bake evenly instead of cracking in random spots.

As the piped circles sit out, the surface dries and forms a thin skin. In the oven, that dry top holds in place while the inside puffs, so the batter is pushed upward and forms the little “feet” at the bottom. Heat then sets the egg whites and almond flour into a light, crisp shell with a slightly chewy center that can hold a filling without falling apart.

Mistakes To Avoid

Overmixing the batter after adding the almond flour mixture quickly knocks out the air from the whipped egg whites. The mixture turns runny and flows like pancake batter instead of slowly folding over itself. In the oven, these shells spread flat, lose their “feet,” and bake up thin and chewy instead of light with a slight crisp.

Skipping the resting time or not waiting long enough for a dry skin to form on top leaves the surface sticky. In the oven, steam pushes through the soft tops instead of out the sides. The shells then crack on top, rise unevenly, and often end up hollow inside.

Letting the oven run too hot or baking too long causes the shells to brown and dry out. The bottoms can become hard and overbaked while the centers turn crunchy instead of slightly soft. Once cooled, they are difficult to bite and don’t sandwich nicely with the filling.

Using almond flour that isn’t finely ground or not sifting it well leaves tiny lumps in the dry mix. These bits don’t blend smoothly into the batter and create bumps on the surface. The baked macarons then look rough and can feel grainy instead of smooth and delicate.
