Dump the ground almonds or almond flour into a small skillet. Turn the heat to medium, and, using a heat resistant spatula, break up any clumps then stir continuously. The almond flour will take a while to toast, but when it does, it happens very quickly. So, don't walk away or check texts, otherwise, it'll scorch. The minute you see the almond flour taking on color, remove the pan from the heat, and continue to stir. If the flour isn't as toasted as you'd like, return the skillet to the heat for a brief bit, remove it, and stir. Repeat until the desired toastiness is achieved, then transfer to a plate to cool completely.
