“I'm obsessed with not chucking away food. I'm lucky enough to have a gardener, so we grow sweetcorn, tomatoes, beetroots, cabbages, pumpkins, lettuce. I'm trying to get into blanching it and freezing so I don't have to buy veg over the winter, but then you need loads of freezers, and that's not ideal.”
