Hass avocados have a pebbly skin that ripens from green to deep purple or nearly black, and they can vary in size from 5 to 12 ounces. Although the skin is thick, it is relatively easy to peel. The flesh closest to the skin is pale green, and as it nears the medium-sized central stone it develops a yellow undertone. The flesh is soft, creamy, and not fibrous, with good oil content. The flavor is rich and nutty with a slightly sweet finish.
