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.
