Sales of air fryers, pressure cookers, slow cookers and even microwaves have been increasing over the past year, and it is not hard to understand why. All these gadgets save energy, which has undoubtedly become more important since energy prices shot up. But can using them do more for us than just save money? In this programme, Sheila Dillon meets people who are obsessed with air fryers, pressure cookers and slow cookers. She hears from Belfast's Nathan Anthony about how his social media account "Bored of Lunch" has propelled his slow cooker recipe book to the top of the charts, and she speaks to Bristol's Square Food Foundation to find out why they are considering introducing pressure cookers on their courses. And could the devices help outside the home too? Hospitality businesses are under pressure with rising costs, and customers with increasingly tighter budgets. In Somerset, chef and restaurateur, Nicholas Balfe tests out some low energy appliances to see if they could make any difference in the professional kitchen. Are you now using a low energy cooker again, for the first time, or more than before? Tell us about what difference it's been making on social media.
