1) Grill the chicken thigh meat skin-side down. Once the chicken is cooked, add sliced onions and two tablespoons of butter.
It is recommended to thinly slice the onions and microwave them beforehand to remove moisture.
2) Add two blocks of solid curry, melt them in oil, and stir-fry a little more.
3) Add about 300ml of milk.
If you want a smoother taste, add more milk.
4) Add chili powder or peperoncino to your liking here.
Once it thickens a bit like this, it's done.
