1. If the red pomelo you buy is sour and bitter, it is generally recommended to use sweet ingredients such as apples and bananas to squeeze the pomelo. This can not only relieve the bitterness and sourness of grapefruit to a certain extent, but also replenish the body. Rich nutrition can improve your own immunity.

2. First prepare a red pomelo, an apple, a banana and an appropriate amount of honey. Then peel the red pomelo and remove the pulp, core and cut the apple into pieces, and peel the banana. Then put the grapefruit, apple, and banana into the juicer, add one-third of the water, and pour in an appropriate amount of honey. It is best to turn on the juicer, squeeze the juice, filter it, and pour it into a cup for drinking.
