‘Potato with yeast and olive,’ trumpeted the waiter. Two thumbnail-sized baby potatoes with a flaky top. ‘Thank you,’ we chirped, shoving them in our gobs like chicks on Springwatch’s kingfisher cam. Next, ‘amaranth with sorrel’ (a small handful of what might be finely milled Trill, set in something sticky), followed by an enormous plate with one tiny girolle in the centre, in a puddle of ‘illuminated cuzo’ (resembles honey). The mushroom sat on my plate eyeing me provocatively. ‘We’ve been here so many times, Grace,’ it said, taunting, ‘but still you can’t behave like an adult.’ ‘Shut up, mushroom,’ I said. ‘I was textbook-standard mature to those people last week who informed me they ate live ants at Noma.’
