My sister, Renata, is a fantastic cook. Unlike me, she’s humble and understated; she doesn’t feel the need to spray her accomplishments all over the internet. But she is supremely accomplished in the kitchen, and a master of comfort food. I don’t mean that in some passive-aggressive denigrating way. Hers is the kind of food you crave when the weather is cold and blowy and you’re feeling a little forlorn. It’s the food you share with family and close friends.
