Pour oil into a wok. (This should create a layer of about 1/4 inch of oil in the wok, depending on the size or your wok. Add some more oil if needed.)
Place wok over medium-high heat until the oil is hot.
While oil is heating crack egg into a small ramekin or coffee cup.
Gently tip egg into the hot oil.
Let the egg fry, without moving it, until the whites start to look firm and cooked through and the edges are bubbly and deep golden brown, 2 to 3 minutes.
When the edges and bottom of the egg are golden brown, use a spoon or wok spatula to scoop up a small amount of hot oil and drizzle it over top of the egg. Do this for about one minute just until all of the whites are fully cooked.
Transfer the cooked egg to a paper towel-lined plate to soak up some of the excess oil.
Serve immediately, while egg is still hot.
