In a clean bowl, whip egg whites with cream of tartar until they get foamy. Slowly add sugar while beating. Keep whipping until you get stiff, shiny peaks, usually takes about 7-9 minutes.

Carefully fold your almond flour mix into the whipped whites. Make sure everything's mixed well but don't flatten the batter.

Spoon batter into a piping bag and squeeze out 1.5-inch circles on a baking sheet lined with parchment. Leave gaps between each one.

Let your piped circles sit out for 30 minutes until they form a dry skin on top.

Take the tray out and wait until the shells are totally cool before you pick them up.
