Place the pan on the stove over medium-high heat. Allow the water to come to a full boil, which should take 3 to 5 minutes. With the rice covered, it should take 10 to 15 minutes for it to cook. When it’s finished, it should still be slightly firm but not crunchy. Don’t overcook the rice, though, or it will become gummy. If you didn’t soak the rice before cooking it, it may take 18 minutes or more for it finish cooking.

How would you rephrase that briefly using Vietnamese?
Đun nồi gạo và nước. Chờ đến khi cơm chín mềm.
