Upgrade your kitchen countertop with this sleek Tower Sera kettle. As well as looking the part, it’s packed with 3 kilowatts of power, which means it can boil enough water for 1 cup in less than a minute. That’ll be great when you’re gasping. But if you’ve got the whole crew round for a brew and biscuits, just fill it right up to make enough for 7 cups. When you’re feeling the pressure to make a good cuppa for guests, it’s good to know the built-in limescale filter has your back. As for the milk ratio – that’s all you. And if you have a habit of flicking the kettle on without checking there’s water in it, this one comes with boil dry protection to stop it getting damaged. Sugar, anyone?
