How to pick a stovetop kettle?
• If you’re looking for a kettle that's durable and is easy to clean, opt for a traditional stainless steel or cast iron kettle. Glass kettles are stylish, but are more prone to cracking.
• Not every material conducts heat in the same way, and this can affect the speed at which your water boils. Copper kettles are more high maintenance as they require regular polishing, but they are excellent heat conductors. If this is important to you, one of the best options would be to choose a stainless steel kettle (which is easier to clean) with a copper bottom.
• If you need to boil a lot of water, look for a kettle that has a large lid and wider spout.
• Not all kettles can whistle, so be sure to check before you purchase.
