Recipe: langoustine with leek, buckwheat and smoked goose agnoletti

Chef Grégoire Berger of Ossiano shares a recipe that includes one of his favourite ingredients: buckwheat

Langoustine, leek and smoked goose agnoletti, brown onion emulsion and buckwheat            

Gregoire Berger, of Atlantis, The Palm’s Ossiano, says: “I love buckwheat, especially in seed-form, dried and fried. It has a wonderful flavour and evokes fond childhood memories. Renowned for its health benefits, buckwheat has a unique nutty and earthy taste. Despite having wheat in its name, buckwheat is, interestingly, gluten-free.” Berger was among the top 10 winners at the Best Chef Awards last year.
