When the pan is hot, add half of the rice with garlic; cook, stirring constantly, resting in between stirring to brown the rice and scrape the bottom of the pan to loosen the rice that has browned and toasted, about 3 minutes. Transfer to a plate and set aside. Into the same pan, add 1/2 tablespoon of oil and the remaining rice, cook it the same way as the first batch, about 3 minutes.
