Peel a squash, grate it and slice it in half. Peel a squash, grate it and slice it.
Melt the butter in a larger pan and fry the quince slices on all sides until golden.
In another well-heated pan, place the chicken pieces and leave them until golden on all sides and almost done. Salt them and pepper them. Put them next to the quince in the large pan.
Pour 3/4 cup of water, put the lid on and leave for a few minutes until the quinces have softened, but they are not fluffy. The meat must also be cooked.
Mix the starch with 2-3 tablespoons of cold water, until it dissolves well. Put it over the meat, and let it boil for 2-3 minutes. Make sure that the sauce hardens very quickly, because quinces contain pectin.
Match salt and pepper.
Optionally you can make a caramel sauce with which to sprinkle quince food.
later edit: I forgot, but I'm telling you now. When you pour 3/4 cup of water, you can put some white wine instead of water. That's what I did. It gives it a special taste.
