My digital thermometer Food writer and owner of Bristol Fire School, Genevieve Taylor picks her kitchen hero

As a barbecue expert and fire cook, I couldn’t live without my temperature probe. The most essential skill of mastering fire-cooking is learning to cook to temperature not time – that’s the internal temperature of your food rather than the temperature of the barbecue. Every fire I light behaves slightly differently and so time becomes irrelevant. Your food is ‘done when it’s done,’ and the best way to know it’s cooked and safe to eat, or just as importantly, not overcooked and dry, is to test its temperature. I wouldn’t dream of lighting my fire without one in my pocket. @genevieveeats
