In Hetty McKinnon’s house, family meals are sacred.
The Australia-born, now Brooklyn-based cook and food writer is plenty busy: Her many hats include founder of salad-delivery business Arthur Street Kitchen back home in Surry Hills, Sydney; creator and publisher of Peddler Journal, a biannual multicultural food magazine; co-owner of Neighborhood Studio, a community kitchen space in Brooklyn; and beloved cookbook author, with her third and latest book, “Family,” released in the United States this April.
