Fried rice comes in a BOX?!?
I simply use the leftover white rice from the Chinese restaurant. You can also buy extra quarts for a dollar or two.
It's best if you rinse it and let it sit overnight in the fridge. This removes the extra starch and stops it from being sticky.

You notice fried rice isn't clumpy & sticky.
Heat a non-stick skillet or stovetop wok/skillet to super hot. If you can't get the stove hot enough, it's not going to work. It also doesn't work well on an electric stove and not at all over those smooth top burners. It's better to call for Chinese delivery. You will just end up with mushy rice that in no way resembles authentic Chinese fried rice.
Add COLD vegetable oil in or peanut oil - NOT olive oil. Olive oil is not indigenous to China. You want authentic flavors, otherwise you will later say, it just doesn't taste the same.

If you use olive oil, that's why.
Heat the oil now, till it's sizzling hot. Lower flame to medium high heat. Add in minced onions & garlic. When the onions turn translucent, add in your PRE-cooked diced meat. (Meat is optional.) Toss, stir. Add in your rinsed, day old rice. Stir fry some more. Add in other veggies, like beansprouts, peas, scrambled eggs. (Yes, I know eggs are not veggies.

)
Keep stirring, or the rice will burn to the bottom of the pan. Add in roughly equal parts salt, soy sauce and
sugar. Chinese food is always a
balance of salty, sweet, bitter, sour, etc. Stir fry some more. Adjust the salt/soy/sugar to taste. It won't be as dark as the rice from a Chinese restaurant. They add an extra thick soy coloring ingredient that purposely darkens and adds a nice brown color to the dishes. It's usually only found in the Asian markets, not regular grocery stores.
Serve.
