This is the all time best comfort food in my opinion...Like your mum's Sunday roast only....I have to say.....even better...sorry mum;) It really is just amazing!
As for entertaining..it's also the best. It can (and should) be made 1-4 days ahead of time and just kept in the fridge. It seems to get even more rich with time! Right before the gathering, warm it up, make a salad and Polenta...and just like that....one of the best meals they will have every had!
