1/2 cup orange juice
1/4 cup maple syrup
A pinch of chili flakes or powder
Salt and freshly ground black pepper
Mix the chicken stock, orange juice, maple syrup and chili flakes together in a small saucepan over high heat. Let it come to a bubble and reduce it by half until it is thick and syrupy, about 5 minutes.
Season with salt and freshly ground black pepper.
