Pre-heat your oven to 375 degrees. Put everything except the egg into your food processor, and pulse/blend until the butter is smaller than pea sized pieces. Add the egg and blend until the dough forms a ball. Pinch off your biscuits, gently roll them, and flatten a bit onto a Silpat or parchment paper lined baking tray. I always make 5 biscuits with this recipe. Bake at 375 degrees for 14 minutes. Let the biscuits cool a good 5-10 minutes before handling so they can set up.
