Preheat your oven to 300°F (150°C) and line two baking trays with parchment paper to keep your cookies from sticking.
02 -
Combine the almond flour and powdered sugar, sifting them together to remove lumps and larger pieces.
03 -
Whip the egg whites until glossy and firm, gradually sprinkling in sugar. Fold in the vanilla and food coloring gently after peaks form.
04 -
Carefully incorporate the almond and sugar mixture into the meringue, folding softly until it flows like lava—neither too thick nor overly runny.
05 -
Transfer the batter to a piping bag and make even one-inch circles on the baking paper, tapping the trays firmly to pop any air bubbles.
06 -
Leave the piped shells at room temp for about 30-60 minutes, until a skin forms on top and they don’t stick to your finger when touched.
07 -
Pop the trays in the oven for 15-18 minutes until the shells are firm and release cleanly from the parchment.
08 -
Once cooled, pair up the shells by size. Spread one with jam, sandwich it with its twin, and add crushed pistachio on top as a finishing touch.
