Summarize this article in one sentence.
Cut it in half, loosen the segments, and eat it straight out of the peel with a spoon.  When you cut the ugli fruit open, the inside should look similar to that of an orange, but the fruit should appear slightly fleshier than an orange would. Unlike grapefruit, the ugli fruit is sweet enough on its own and does not need any added sugar. If you do add sugar to the fruit, you may even find it too sweet. An ugli fruit can be enjoyed in this manner as a simple, light breakfast. If you want to use the fruit for a light yet exotic lunch or dessert, you can cut it in half and drizzle it with a bit of sherry or kirsch before enjoying it. Peel the skin off the ugli fruit and separate it into sections, like you might expect to do with a tangerine. The segments can be eaten one by one.  The skin is thick yet loose and puffy, so you should be able to remove it with your fingers. There are seldom any seeds, so you should not have to worry about removing seeds before enjoying the fruit. The segments inside the fruit are also easy to separate, and you should be able to separate those with your fingers, as well. Enjoy the fruit in this manner as a snack or side dish to your breakfast, lunch, or dinner.

Summary:
Eat the ugli fruit with a spoon. Peel and separate the segments.
