Throughout the demonstration, Kerth gave guests step-by-step instructions for creating the dish. During the demonstration, guests were able to discuss techniques and ask the Chef questions concerning his career, menus and the culinary industry.

To start, he created a sweet pickling liquid made from water, chardonnay and sugar. A large cod was filleted and salted for 10 minutes, then rolled in clingfilm and left to set.

Broccoli stems was shaved thinly and placed in ice water to curl up, before dicing the stems into cube-sized amounts, and once done, it was added to the pickling liquid. At this point, keeping the broccoli raw, the tender stem broccoli was salted in water until al dente, then plunged straight into ice water.

Broccoli purée was made from chopped broccoli, water, olive oil, unsalted butter, salt, caster sugar and baby spinach leaves. This mixture blended in a food processor until it was a beautiful smooth consistency.

A smoked oyster mayonnaise was created from egg yolks, mustard and vinegars in a food processor and blended for two minutes. Then it was blended again with oysters added, and whilst the motor was running, smoked oil was gradually added to thicken the mayonnaise.

Next, a gnocchi was made, by baking potatoes at 180°C for an hour, and once it was taken out of the oven, it was mashed with egg oil, squid ink and salt. Then in a second mix, parsley flour and parmesan were set aside. On a work surface (or deep bowl), these ingredients were poured in the middle and kneaded together to form a dough. The dough was then rolled into thin logs and cut and shaped into gnocchi.

The gnocchi were blanched in boiling salted water until it floated to the top, then refreshed in ice water, then drained and drizzled with olive oil.

Next sweetcorn kernels were made, followed by confit lemon, and the dish was assembled by arranging the ingredients on three large round bowl plates. All guests thoroughly enjoyed samples of each dish Kerth created.
