MAKE-AHEAD OPTION: I haven’t tried this, but the original recipe notes that the uncooked falafel patties can be refrigerated on a parchment-lined baking sheet, wrapped tightly in plastic wrap, for up to 2 hours before baking.
HOW TO DOUBLE THIS RECIPE: Preheat the oven with two oven racks near the center of the oven. Double all of the ingredients. If you have a large food processor (guessing 11+ cup capacity), you can mix all of the ingredients at once. Use two baking sheets, and swap their positions (top to bottom, bottom to top) when you flip the falafel halfway through baking.
