Avocados vary widely in weight, texture, shape, and thickness of skin. When choosing an avocado avoid those that have dark, soft spots on their surface. As for quality or flavor size, shape and color have no impact. To pick out a ripe avocado, put light pressure from your fingertips on the outer rind. If it yields, it's ripe.
Limitation of the use of avocados is that of the users imagination. The most popular avocado dish is guacamole but can be used in or on sandwiches, hot dishes such as soups, stews and omelets just before serving.
