Because the chickpeas need to be totally raw before the falafel balls are formed, the standard quick-soak method of bringing the beans to a boil and letting them sit for an hour will not work with this recipe.
Dried Chickpeas
Starting with dried chickpeas is an automatic improvement in flavor. Just like with making hummus, I’ve found that dried chickpeas have a cleaner, more straightforward chickpea flavor, while canned chickpeas can get a tinny, skunky taste to them. If you cook those dried chickpeas before making falafel, you run into the same issues you find with canned—they just don’t bind. Because the chickpeas need to be totally raw before the falafel balls are formed, the standard quick-soak method of bringing the beans to a boil and letting them sit for an hour will not work with this recipe. The key to great falafel is to soak the dried chickpeas, but grind them while they’re still completely raw.
