What to do with your kid when you can’t go out due to the Italian lockdown? Make Celeriac chips, of course :-) We cut the root very thinly, then mixed up melted coconut oil, tumeric, nigella seeds, black pepper and a little cumin. He’s painting the yellow on and then I’ll bake them in a hot oven, turning half-way, for about 35 mins. It’s important, I remind him, to space them out to help them crisp up.
