Step 1: Gather your ingredients
You will need Almond flour or almond meal, which is basically pulverized almonds, Trader Joe's has the best price, or you can grind your own in a food processor, in that case, use blanched almonds for a more pure look, Trader Joe's almond meal makes pretty speckled cookies.
Either granulated or superfine/caster sugar
Egg Whites, from a carton is fine, no need to mess around with aged egg whites
Cream of Tartar
Optional, Food safe gel dye
IMPORTANT, use a scale. I tried it with volume measurements several times and the only time it worked I just got lucky. Go ahead and buy a scale, they're like 4 bucks at Target, you don't need a fancy digital one, an analog one will work just fine.
Step 2: Weigh ingredients
Weigh out 15 grams of granulated sugar.
In a bowl weigh out 50 grams of egg whites.
Pour the egg whites into the mixer and put in a dash of cream of tartar, I like to measure it using the lid. Dump in the caster sugar. Start the whisk out slowly and then increase the speed as it starts to get foamy until you're at 10 on your mixer.
While this is beating up, go to the next step as you need to work quickly and simultaneously.
