Tips
Toast the peanuts in a dry pan first to enhance their nutty flavor and add extra crunch to the finished dish.
Cook the ground beef undisturbed initially to develop a good sear before breaking it up for better texture and flavor.
Add chili flakes gradually to taste since heat preferences vary, and you can always add more but cannot remove it.
