Can I use a different cut of steak?
Yes. Flank, ribeye, or New York strip work well. Avoid very tough cuts; cube and cook quickly over high heat for tender results.
Should I use fresh or day-old rice?
Day-old refrigerated rice is ideal—it's drier and won't clump. Fresh rice can work if spread on a plate to cool and dry slightly first.
How do I prevent the steak from being tough?
Cut against the grain into even cubes, and cook over high heat just until browned. Don't overcook; it will continue cooking when mixed with the rice.
Can I make this ahead?
Cook the steak and fried rice separately, then store in airtight containers for up to 3 days. Reheat the rice in a skillet with a splash of oil; warm the garlic butter sauce separately and drizzle before serving.
What if I don't have brown sugar?
Use white sugar or honey in equal amounts. Brown sugar adds mild molasses depth, but white sugar will still balance the soy sauce.
