In the same pan, increase heat to medium-high and cook ginger and red pepper in garlic oil, stirring occasionally, until just softened and fragrant, about 2 minutes. Add egg and stir to break up; cook for 10-15 seconds – just long enough to set egg. Add rice and sesame oil. Toss to combine. Cook, pressing down on rice with a spatula until rice begins to crisp, about 2 minutes. Toss in the pan, then press down on rice again, cooking for another 2 minutes. Remove skillet from heat and toss in scallions and half of fried garlic; season with salt.
