This was extremely nice and I would do it again in a flash, or in a carefully simmered 6 or so hours, as the case is here. The one important thing to note is that the recipe recommends removing the skin, an action I assumed was overly health conscious piffle.
Not so! Turns it over such a time scale the skin renders down turns everything pretty fatty.
It's not impossible that cooking the rice separately would be preferred here, but that sort of goes against the ethos..
