Hearts of palm are the edible inner portion of the stem of the cabbage palm (Euterpe oleracea) - the same tree that produces the açaí berry.
These delicate, ivory-colored gourmet treats resemble white asparagus, sans tips. They have a firm, smooth texture and a flavor similar to an artichoke. Each stalk is about 4 inches long and ranges in diameter from pencil-thin to 1 to 1 1/2 inches.
