Unlike its competitors, the Cuisinart mini chopper has dual holes nested in a deep channel across the lid; the others have just one. This makes it easier to continuously drizzle olive oil into my vinaigrette without shutting it off, scraping the sides, or even paying much attention to my pour. And that continuous, steady stream flowing into both sides of the work bowl results in a quick, thick, evenly mixed batch of anything creamy. (In their tests, my colleagues found that this processor excels at making homemade mayonnaise.)
