Bring water in a big pot to a boil. Buddha's Hand in Dice, bring back to a simmer, and cook for 30 minutes or until citrus is tender. Drain.
Buddha's hand, 2 1/2 cups sugar, and water should all be combined in the same pot. Bring to a simmer and cook, occasionally stirring, until the syrup reaches 230 degrees F. (110 degrees C). Once room temperature has been reached, remove from heat. Citrus should be drained; the liquid should be saved in jars.
Spread out the drained citrus on a wire rack and allow it to air dry for at least 24 hours or until sticky. Fill a small bowl with the remaining sugar. Citrus should be covered with sugar and then transferred to a dish to dry for at least two hours.
