Fry the chicken. It doesn't need to get cooked all through since it will later boil in the sauce.
Move the chicken pieces to a pot and add sambal oelek (or chopped chili fruit).
Add soy and water.
Add chicken broth.
Simmer for a few minutes.
Add the chopped leek..
..as well as the mango chutney.
..and add the creme fraiche.
Stir again. Heat it up and then you're almost done, just a last detail is added..
..and that's the fresh mango. How I love this fruit! Once you add the mango don't let it boil or the fruit will dissolve.
Here we have the final result. Best served with rice.
