Native to South America, pineapple guavas (also know as feijoa sellowiana and guavasteen) are newly in season. I picked some up at my local Farmer's Market yesterday. These egg-shaped fruits are green in color and feel firm to the touch, so it's hard to tell that they're ripe and ready to eat. The farmer I bought them from waits for the fruit to drop on its own from the tree as that means they're ripe. She was giving samples and I liked the tangy flavor. She told me that most people scoop out the pulp, but that it's good also to eat the skin. I tried that, and found it chewy and kind of gritty but with good flavor. If you can get your hands on pineapple guavas, give them a try -- and give your palate a chance to become acquainted with new exotic flavors.
