Pomfret with mashed potatoes

We arrive at a pop-up in Madh Island called Aal's Kitchen just after a party has ended there. Alistair Lethorn, the home chef who's hosting it, tells us that over the past few hours, around 60 people have been in and out of his 2BHK. The emptied glasses and bottles of beverages left behind wrestle for space on the kitchen table. The sofas are vacant, but still warm, and the house feels as if it's finally breathing easy after the constant banter of foodies packed within its walls, sharing drinks and dinner apart from conversation. Now, there is a quietness settling in, broken only by a chat that we start with Lethorn before the chef serves us the final helping of food remaining.
