At Cub Foods, the produce department sells 1 to 2 cases a day of this unique, nutty-flavored vegetable. In fact, Chris Wagner, produce manager at Cub Foods, has noticed a growing consumption of all fruits and vegetables. One medium artichoke has just 60 calories. Choose artichokes with soft green color and tightly packed leaves. Size has little to do with quality or flavor.
Small artichokes are just a smaller bud.
Though artichokes are best used the day of purchase, they will look and taste fresh for up to two weeks if handled properly. Do not wash before storing. To keep longer than a few days, just drizzle a few drops of water on each artichoke, place in a plastic bag, seal airtight and refrigerate at 32 degrees. Pull off lower outer petals and use a sharp paring knife to evenly trim the base. Snip off the tips of petals, if desired, and to prevent browning, rub all cut edges with lemon juice.
