Upon further research of this freak fruit, I found that it's not used for the small amount of acidic juice inside, but for the zestful flavor of the rind. The peel is used for flavoring meals, scenting perfumes, and infusing flavor into vodkas and other liquors.
Check it out, and enjoy some to spice up your next stir-fry dinner or to add some zest to a homemade sangria!
