My Nigerian brother-in-law introduced me to beef suya, a very spicy street food that's popular in western Africa. I was intrigued when I found out the spice rub is made from ground peanuts and a blend of different seasonings. After lots of experimenting, I came up with my own version. —Elena Iorga, Irvine, California
