Pineapple guavas vary in color and texture of the skin. To test if the fruit is ripe, squeeze the fruit. It is ripe if it has a bit of give and a rich fragrance. If the fruit isn't ripe, ripen it in a paper bag with an apple, or leave it out on the counter for several days. The ripe fruit can be refrigerated for 3 to 5 days.
Use a knife to cut the feijoa in half. The blue-green skin is bitter and should not be eaten raw. It can be used as an ingredient in preserves.
Use a spoon to scoop out the pulp from the center of the fruit. The center has thick, juicy flesh that is light yellow or white in color. There are also about 30 edible seeds in the jelly-like center. A feijoa fruit has a taste reminiscent of pineapple, banana, strawberry, guava and quince. The flesh of the center may be eaten raw. It is often eaten in fruit salads, preserves and syrups.
