I've made this twice now, and everyone loves it every time. I make sure to use natural peanut butter for less sugar and more peanut flavor. i also add cumin, salt, and pepper to make it suit our tastes. it's a great base recipe, and if you know your curries and seasonings, you can make it amazing!
*edit* I made this in my instant pot by sautéing the chicken until browned, them added the other ingredients, and put it on for a 7 min pressure cook. it turned out better than it has on the stove top!
