A burr grinder works even better than the bladed coffee grinders, giving a more consistent full grind ,but they can be hard to find for a reasonable price. I lucked out and found an oster for $19.99 at a liquidation store we sometimes go to.
Or you could go Old school and visit an asian grocery store and buy yourself a big stone mortar and pestle .. Very cool sitting out on the counter and a great way to bash up large quantities of garlic fast.. plus it makes the best pesto ever .
the texture of food processor pesto just isn't the same.
