These first-quality mini beans were originally developed for upscale European markets and sold for top prices to fine restaurants. Nickel beans are produced in abundance on sturdy compact plants and mature at just 3 to 4 inches long and 1/4 inch in diameter. The tender pods need only brief cooking and little extra adornment. They will grace your plate and palate steamed and tossed with a little butter and fresh herbs or sautéed and sauced.
