JESSIE Instagram can sometimes be good for the soul, especially when it comes to food. My friend once posted a night out, showing a butter-poached new potato with a little sour cream and caviar on the top. It looked equally ludicrous and divine. So I decided to try butter poaching, but adding something extra. I bought smoked rapeseed oil from a local farmer at the Bridport Food Festival and it has been the best addition to nearly everything. Serve these butter-poached roast potatoes with simple pan-fried fish and salad or dress them up with sour cream and caviar.
