JOAN ROCA’S MARINATED MACKEREL WITH BOTTARGA

By  |  0 Comments

Over the years, Chef Joan Roca has served as a mentor and inspirational figure for countless young chefs around the globe. The restaurant he runs with his brothers, El Celler de Can Roca in Girona, Spain, was voted No.1 in The World’s 50 Best Restaurants in 2013 and 2015. This year, he still placed remarkably high at number three in the World’s 50 Best Restaurants.

But accolades aside, the humility with which Roca cooks his astonishing food is quite extraordinary. Talking at the Estrella Damm Gastronomy Congress in Melbourne ahead of the World’s 50 Best Restaurants, he spoke of how he and his family lived above El Celler De Can Roca, and how he and his staff still eat every day at his parents’ humble and long-running bar and eatery down the road from his restaurant, called Can Roca, to remind himself and his staff of their beginnings.

Here, Roca shares with us a zesty, flavoursome fish recipe from his incredible restaurant back home in Girona. Cooks take note: this is a challenging recipe, but the results will be worth it!
