Guava (Ripen at Home)
The guava fruit tastes like a combination of strawberry, pear, and even mango. It has a sweet taste once it is ripe. Unripe guavas are sour, and the outer skin will have a sweet-sour taste. Some of the varieties are sweet and can even taste like a cross between grapefruit and pear together.
Guavas are an excellent source of vitamin C and potassium.
