Chestnut Spice Argentine Macarons (Egg-Free, Autumn)

What Makes This Special

This recipe adapts the classic French macaron method to Argentine flavors, using chestnut flour and a blend of warming autumn spices. It uses aquafaba instead of egg whites, retaining the signature chewy shell and smooth surface, and is filled with dulce de leche for a distinct regional element.

Ingredients

This macaron replaces some almond meal with chestnut flour for an autumnal, nutty base. The spiced blend references local dulces and the rustic feel of Argentinean autumn. Aquafaba provides the structure normally handled by egg whites, though it will be slightly less stable. Dulce de leche is the classic Argentine filling.

For the Shells

• Chestnut flour: offers a copper hue and mild earthy flavor
• Ground almonds: retains texture and classic macaron structure
• Icing sugar: keeps dry ingredients fine and prevents lumps
• Spices: cinnamon, nutmeg, clove for autumn warmth
• Aquafaba: whipped to soft peaks, mimics egg whites
• Cream of tartar: stabilizes the meringue
• Caster sugar: helps create a glossy meringue
• Vanilla extract: rounds out flavor

For the Filling

• Dulce de leche: thick, sticky, classically Argentine
• Chestnut pieces (optional): for extra texture

Instructions

Step 1: Prep Dry Ingredients

Sift the chestnut flour, ground almonds, icing sugar, cinnamon, nutmeg, and clove together into a large bowl. This ensures a fine, lump-free powder that leads to smooth shells. Discard large almond pieces left in the sieve.

Step 2: Make Aquafaba Meringue

Pour the aquafaba into a clean mixing bowl. Begin whipping on medium speed; once foamy, add cream of tartar. Increase to high speed and add caster sugar gradually, whisking until stiff, glossy peaks form. Add vanilla and mix briefly. The meringue must be stable or the shells will collapse during baking.

Step 3: Macaronage (Folding Technique)

Add the sifted dry mixture to the meringue in two batches. With a silicone spatula, fold gently: cut down through the center, sweep around the side, and turn the bowl with each fold. Repeat 40-50 times, or until the batter flows slowly off the spatula in a thick ribbon and settles back into itself within 15-20 seconds. This critical step determines shell structure: undermixing leaves peaks, overmixing makes the batter runny and causes flat, cracked shells.

Step 4: Pipe and Rest

Transfer the batter to a piping bag fitted with a 1 cm round tip. Pipe 3.5 cm circles onto lined trays, leaving 2 cm between each. Rap trays firmly on the counter 2-3 times to remove air bubbles. Optionally, sprinkle a few chopped chestnut pieces onto half the shells for garnish. Rest trays uncovered for 45-60 minutes, until shells look matte and feel dry to a gentle touch. This forms a skin so the tops bake smooth.

Step 5: Bake

Preheat oven to 120°C (fan-assisted) / 130°C (conventional). Bake trays for 22-25 minutes, rotating once halfway. Shells are done when they lift cleanly from parchment and feel firm. Cool completely on tray before handling.

Step 6: Fill and Assemble

Pair shells by size. Pipe or spoon 1 heaped teaspoon dulce de leche onto half of the shells. Sandwich with their partners. Do not overfill; dulce de leche will ooze if pressed too hard.

Step 7: Maturation (Optional)

For optimal texture, refrigerate assembled macarons in an airtight container for 24 hours. Moisture from the filling will soften the shells slightly for the classic chew.

Pro Tips

• Use aquafaba from unsalted chickpeas only; salt or additives destabilize the meringue.
• Sift dry ingredients twice for the smoothest shells.
• Master the folding: stop at thick, slow ribbons; overfolding is irreversible.

Troubleshooting

Shells cracked? The batter was undermixed or the shells were not dried long enough. Rest longer or fold more next time.

Shells flat or hollow? Overmixed batter or an oven that is too hot. Check oven temperature with a thermometer and fold less.

Shells stuck to parchment? Underbaked. Bake for 3-5 minutes longer and cool before removing.

Variations

• Swap dulce de leche for chocolate ganache or chestnut paste for a nut-forward filling.
• Add orange zest to the shells with the spices for a citrus note.
• Omit spices for a plainer chestnut-almond shell, if preferred.

Storage

Store macarons in an airtight container in the fridge for up to 4 days. Bring to room temperature before eating for best texture. Unfilled shells can be frozen, layered between parchment, for up to 1 month.
