Mangosteen

 

Mangosteen are grown primarily in Southeast Asia and southwest India. The white, pulpy edible segments inside are tangy, cool, and slightly sweet, while the dark purple hard exterior needs to be pulled away.

Identify this fruit:


Jackfruit

Jackfruit is the largest tree-borne fruit in the world, weighing up to 40 pounds or more. Luckily, you don’t need to throw this massive fruit into your shopping cart. Some health food stores carry peeled and cut jackfruit portions in pouches or cans, ready to cook or eat.
