Barbecued beetroot cooked directly on hot coals, cut into neat cylinders and rolled in a hogweed seed and oat crumble, served with a caramelized Jerusalem artichoke puree, an aerated Jerusalem artichoke veloute, burnt apple puree deglazed with apple juice, diced apple with parsley and dill, and deep-fried Jerusalem artichoke peel crisps. The dish was presented with a crossword card as a nod to code-breaking methods. Jeff described his approach to the beetroot: 'There needs to be like proper leathery, real deep in flavour. It is imperative. Otherwise I am literally just giving Simon Rogan roasted beetroot.' On the hogweed crumble: 'Just gives it that kind of clovey smell to it as you are eating it.' He described the burnt apple: 'It is meant to add some intense bitterness to the dish. Burnt apple and deglaze it with apple juice. Get all those nice brown bits from the bottom.' He noted during service that the apple puree came out thinner than intended. The hogweed seeds were roasted with oats to ensure they were safe to eat before use. Veteran Simon Rogan scored this dish 6.
